Mouse down triggers input

[srancour]

Describe the defect

Any input buttons in the edit experience trigger on mouse down, which causes the buttons to fire no matter if it's a right or left click and no way to cancel the press breaking WCAG 2.5.2 Pointer Cancellation.

To Reproduce

Steps to reproduce the behavior:

1. Go to a page like a VAMC Detail Page that has an <input> button like the Featured content Add Page-Specific Q&A button
2. Go to edit screen
3. Right or left click and hold on any of the Add, Edit, or Remove buttons
4. See button trigger on mouse down

AC / Expected behavior

The button should only trigger on left click and should wait until the mouse up trigger instead of mouse down.

Additional context

This is an issue captured within Drupal Core and does appear to be under active development, but the last update was June 2024. From that ticket it seems to be related to the ajax trigger.
