Holding down ALT to duplicate/drag objects doesn't work (on linux)

[thibaultmol]

Describe the bug When trying to duplicate/drag objects using the ALT key, nothing happens

To Reproduce Steps to reproduce the behavior:

1. Open a new excalidraw drawing
2. create an object
3. hold down ALT and drag it
4. nothing happens

Expected behavior Drag the object as the button is held down

Environment (please complete the following information): Operating System: Garuda Linux KDE Plasma Version: 5.25.4 KDE Frameworks Version: 5.97.0 Qt Version: 5.15.5 Kernel Version: 5.19.1-zen1-1-zen (64-bit) Graphics Platform: X11 Processors: 16 × AMD Ryzen 7 3700X 8-Core Processor Memory: 31,3 GiB of RAM Graphics Processor: NVIDIA GeForce GTX 1080/PCIe/SSE2

Additional context

• If I go into the hotkeys tab in the settings, the application does detect 'alt + ' key combo's
• https://en.key-test.ru/ in both firefox and chrome also detect ALT correctly
• I have tried all keys, CTRL, SHIFT, ALT, ALT GRP, META. But none perform duplication dragging.
• Trying to ALT drag does make the cursor icon stay on the 'dragging' icon. Video of me trying to alt grab (at one point I let go of alt just to show that normal dragging works) https://imgur.com/a/fp4aI55

Can you try adding the following code in developer console (CTRL+SHIFT+i) and let me know what the output is when you press the ALT button while working in Excalidraw?

window.addEventListener("keydown",(e)=>console.log(e))

After the test it will be probably best to restart Obsidian to get rid of the code.

This is the sort of output I am hoping to see:
