Move to front/back keyboard shortcuts not working on Mac with British and British - PC keyboard inputs

[mitches-got-glitches]

Hello, I'm on Mac TahoeOS v26.4 using the extension version 3.9.1 (most current). The keyboard input I'm using is British - PC but same issue occurs on British also.

The following keyboard shortcuts don't do anything.

• Send to back: Cmd + Option + [
• Bring to front: Cmd + Option + ]

Many of the other shortcuts work, including copy and paste style (with Cmd + Option used). And VS Code I've checked and nothing else is eating my shortcuts.

I've tried to inspect what is going on via the Dev Tools pane and this might provide some answers on whether it is a bug?

keydown: [ BracketLeft meta: true prevented: false
index-B5SVTvzp.js:150 Canceling as multiple actions match this shortcut 
{name: 'sendBackward', label: 'labels.sendBackward', keywords: Array(3), icon: {…}, trackEvent: {…}, …}
{name: 'sendToBack', label: 'labels.sendToBack', keywords: Array(3), icon: {…}, trackEvent: {…}, …}

keydown: ‘ BracketRight meta: true prevented: false
index-B5SVTvzp.js:150 Canceling as multiple actions match this shortcut 
{name: 'bringForward', label: 'labels.bringForward', keywords: Array(3), icon: {…}, trackEvent: {…}, …}
{name: 'bringToFront', label: 'labels.bringToFront', keywords: Array(3), icon: {…}, trackEvent: {…}, …}
length

So it seems to clash with the other shortcut?

[edit] - I've just discovered that "Cmd+Option+Shift+[" solves the issue, same for "]" too - but this isn't what's shown in the Excalidraw UI.
