Inconsistent Keymapping between web version and Windows app

Steps to reproduce

Set a custom keyboard shortcut from either web version or Windows app (here on French keyboard layout), f.i. Ctrl+! to “expand/collapse”

Expected result

Shortcut should be correctly interpreted and applied by both web version and Windows app

Actual result

I have to set two shortcuts (good thing there can be many), one for web, one for desktop app.
When setting the same shortcut (Ctrl+!), it is detected as “Ctrl+EXCLAMATION” by web version, and “Ctrl+KEYCODE_223” by Windows desktop app.

Environment

Windows 10 Pro 2004 (19041.630)
Web version on Firefox 82.0.3 (x64)
Windows desktop app v1.4.2

Does this also happen on Chrome? I think this is a browser-dependent issue and sadly isn’t something we can easily fix without making complicated workarounds…
