Tab switching: cmd+option+left/right arrows oddly stop working after some period of regular usage

Steps to reproduce:

Most browsers in windows/mac/linux have the default universal tab-switching keyboard shortcut of ctrl+tab and ctrl+tab+shift. But macOS browsers seem to have an additional default tab-switching shortcut of cmd+option+left/right arrow.

On Orion RC (undetermined if it applies to Orion), it seems like tab switching via this shortcut stops working after maybe 30-60+ minutes post orion startup. I have never ran into this issue with any other browser.

***These may not be the exact/only steps (although I've tried finding them out). Reproduction is shaky at best in my experience, and while I’ve unintentionally reproduced the issue around ₅-10 times so far, there were times when I’ve doubted whether this was even an issue to begin with. There have been browsing sessions where I wasn't able to reproduce it.

1. Launch Orion RC, and notice that the browser-style tab switching (with cmd+option, not ctrl+tab) works initially
   1.5(?). Install the onetab extension and run it.
2. After some time period (of possibly around 30-60 min of regular usage), suddenly that same kb shortcut doesnt work anymore. I'll add further clarification on the steps and time period if I find that out.
3. The tabs I had open and were using in that time period were majority youtube, some orionfeedback and instagram. I have not seen the issue be reproduced by idling in an empty new tab page.
4. Sleeping macOS doesn’t seem to fix it. Restarting Orion does.

Possibly important notes:

1. In this state, mouse cursor seems to disappear when kb shortcut pressed (unless it's moving at the same time)
2. In this orionfeedback window, while the textbox cursor is active: When trying to invoke cmd+opt+arrow, the cursor jumps between start and end of current line, which is what only cmd+arrow is supposed to do (not cmd+arrow AND option). And by arrow I mean only left/right for this entire report.
3. When the mac cursor focus switches back to orion after some idle time (also unknown # of minutes), the first 1-2 cmd+opt+arrow presses does work, then stops working.
4. The following feature request https://orionfeedback.org/d/1845-support-cmd-shift-leftcmd-shift-right-to-switch-tabs-matching-safari is a bit different using shift rather than option, but neither orion nor safari seem to work with this on my end anyways. So it might be irrelevant.

Expected behavior:
On all the mainstream browsers, cmd+option+left/right arrows will switch between tabs
This is the same as what ctrl+tab and ctrl+shift+tab does, except on orion it's continuing to work, unlike cmd+option+arrow

I forgot to disable all extensions in this recording. I'll comment if I manage to trigger the bug with all extensions disabled.

The second media above shows what cmd+option+arrow does in an google sheets environment. This didn't happen when the main issue of this bug report was reproduced/triggered. But it might be loosely related. Maybe Orion isn't correctly prioritizing the kb shortcut behavior over the webpage/webapp kb shortcuts. When I am able to switch tabs, I switch into that google sheets tab, then get stuck in it because it 'caught' that kb shortcut to do what it wanted with it. I don't know if the word "precedence" would apply here.
