The modal gate returns before event.preventDefault(), so a key combo the app owns is handed back to the browser whenever any dialog is open. Ctrl+S then opens the browser's own save-page dialog instead of saving the workflow, which is what FE-1188 reports and why Ctrl+S 'doesn't always save'.
The modal gate returned before event.preventDefault(), handing a combo the app owns back to the browser whenever any dialog was open. Ctrl+S then opened the browser's save-page dialog instead of saving. Suppress the default for Ctrl/Cmd combos only. Bare keys still reach inputs inside the dialog, which is what the gate was added to protect. - Fixes FE-1188

📝 WalkthroughWalkthroughModal keybindings now prevent browser default actions for Ctrl-modified shortcuts while dialogs are open. Bare keys continue to reach dialog inputs. Unit and end-to-end tests cover Ctrl+S and Cmd+S behavior. ChangesDialog keybinding behavior
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🔵 Low · up to The PR prevents Ctrl/Cmd shortcuts from falling through to the browser while a dialog is open, avoiding unwanted browser actions. Merge risk is low, but the test should also verify that the application save command is not executed in this guarded case.

This would block ctrl+a to select all in a textarea in a modal, right?

No. Ctrl+A/C/V/X/Z in text inputs return earlier through isReservedByTextInput, before the modal guard, so text selection and editing remain native inside a textarea.

Yes. Production intentionally applies this to any modal recognized by isModalOpen; Save As is the regression scenario covered by this browser test.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Assert that the command does not execute.
This listener records only event.defaultPrevented. A handler that runs the save command and then calls preventDefault() would pass this test. Add an observable command-execution signal and assert that it remains unchanged after Line 256.
As per path instructions, browser coverage must include “no command execution.”

Remove the unnecessary type assertion.
Line 151 widens the test-case array with as. Let TypeScript infer the cases, or use satisfies if validation of the case shape is required.
As per path instructions, “Do not use any, as any, or unnecessary type assertions; prefer type narrowing.”

Summary
Ctrl+S sometimes opened the browser's own "save page" dialog instead of saving the workflow. Root cause: the global keybinding handler's modal gate returns before
event.preventDefault(), so any combo the app owns is handed back to the browser whenever a dialog is open.src/platform/keybindings/keybindingService.ts:53-57isModalOpenis true for any managed dialog, any[role="dialog"][aria-modal="true"], any open Reka dialog, any<dialog open>, and any visible.comfy-modal— so this fires often, and intermittently, which is why the report is "Ctrl+S doesn't always save".Changes
preventDefaultis not called for bare-key bindings still pass unchanged.Review Focus
keyCombo.ctrl, whichKeyComboImpl.fromEventsets fromctrlKey || metaKey, so Cmd on macOS is covered.RESERVED_BY_TEXT_INPUT(Ctrl+A/C/V/X/Z/…) already return earlier when focus is in an input, so this does not intercept text editing.How
keybindingService.ts: suppress the default for Ctrl/Cmd combos inside the modal-gate early return.keybindingService.dialog.test.ts: failing repro committed first (test:commit), then the fix — the diff proves the bug existed.browser_tests/tests/defaultKeybindings.spec.ts: e2e opens the Save-As dialog with Ctrl+S, then asserts a second Ctrl+S isdefaultPrevented.Fixes FE-1188 (https://linear.app/comfyorg/issue/FE-1188/bug-ctrls-triggers-browser-save-as-html-instead-of-comfyui-native-save)
