Back and forward keyboard shortcuts sometimes don't work

Steps to reproduce:

• Click a few links to build a page history
• Go back one step (using shortcut or button)
• Cmd + ] now does not work to go forward
• Go back once more (so you have two pages in the forward history)
• Press the forward button
• Now Cmd + ] works

Expected behavior:
Shortcuts always work

Orion and macOS:
Version 0.99.108.1-beta (WebKit 613.1.10)
macOS 12.0.1 (21A559)
Compatibility mode ON
Extensions (disabled):

• Dark Reader
• BitWarden

Notes:

• Safari doesn't have this issue
• Happens with Compatibility mode off and on
• The back button, History > Back/Forward menu items, and Cmd + ArrowLeft/ArrowRight always work
• When the shortcut doesn't work, you get that little "bop" sound like you are trying to do something that isn't possible
• The Cmd + [ shortcut also doesn't work sometimes but somehow it feels harder to trigger this
• I had Karabiner-Elements and BetterTouchTool running initially; I disabled both of them in case the user input stuff they do was interfering but issue remained
• Feels like an off-by-one kinda thing
