Bug: MacMoon and arrow keys

[theJman]

Possible bug with the MacMoon theme...

PM version: 26.2.1
OS: Win7 x86

Problem: when you click on a tab with the mouse and then use the keyboard up or down arrow keys the contents of the webpage doesn't scroll, the expected behavior. Instead, the arrows switch to an adjacent tab.

Is that how the theme was developed, or is this a bug perhaps?

Can't confirm this issue, works as expected.

Please try again with a clean profile; perhaps an addon is causing this?

Just tried it again with cache cleared, all add-ons disabled and in safe mode. I still get the same thing.

Hmm, after a bit of further testing I can confirm it happens. It does appear to be related to how the theme was created. With that said, however, it does appear to be a useful accessibility feature, as you can press the tab key to focus on the active tab like a text field, then cycle through tabs with the arrow keys.

It's a bug for sure, but...a good one maybe? Depends whether anyone would object to this "feature" being removed, really.

Not sure I would classify is a "useful accessibility feature". Seems more like a "dysfunctional interface". Either way, it's too non-standard for me to get comfortable with. Shame too, because overall I like the theme.
