Description

When I'm on the "Easy Checks" page, my browser keyboard shortcuts aren't working: shortcuts such as alt+d (go to address bar), ctrl+f (find on page), and ctrl+r (reload page).

I saw this behaviour in Chrome, Firefox, and Edge.

I don't know if this is related, but I see this error message in the Chrome devtools console every time I press alt+d:

ableplayer.min.js:3 Uncaught TypeError: Cannot read properties of undefined (reading 'prefAltKey')
    at AblePlayer.getAvailablePreferences (ableplayer.min.js:3:35392)
    at AblePlayer.updateCookie (ableplayer.min.js:3:34941)
    at AblePlayer.handleDescriptionToggle (ableplayer.min.js:3:136313)
    at AblePlayer.onPlayerKeyPress (ableplayer.min.js:3:178479)
    at ableplayer.min.js:3:407
    at dispatch (jquery.min.js:3:10316)
    at q.handle (jquery.min.js:3:8343)

and this error message every time I press ctrl+f:

ableplayer.min.js:3 Uncaught TypeError: Cannot read properties of undefined (reading 'length')
    at AblePlayer.handleFastForward (ableplayer.min.js:3:132650)
    at AblePlayer.onPlayerKeyPress (ableplayer.min.js:3:178566)
    at ableplayer.min.js:3:407
    at dispatch (jquery.min.js:3:10316)
    at q.handle (jquery.min.js:3:8343)

I saw some other error messages in Firefox - not the same messages as Chrome, but also mentioning "ableplayer.min.js".

My keyboard shortcuts work normally on this ableplayer demo page.
