[Bug] WebPWA breaks titlebar UI in Firefox taskbar tabs

What happens when the bug or crash occurs?

WebPWA correctly or incorrectly hides the titlebar, but there are no additional controls to replace it. Makes Inbox/Settings/Help/Update icons 1 pixel tall

What is the expected behaviour?

I do not expect broken UI behaviour in the default vencord settings

How do you recreate this bug or crash?

1. Run vencord through userscript
2. Add Discord to taskbar with Firefox (https://support.mozilla.org/en-US/kb/web-apps-firefox-windows#w_install-web-apps)
3. Open Discord (may need to navigate manually to /app )
4. Examine issue
