Feature request: Add a (Google Spreadsheet) anti focus stealing option on tab switch

[mikedotdev]

Describe the bug If you have a Google Spreadsheet Tab open in the background and want to switch tabs e.g. with h and l it will go into "insert" mode and start typing.

To Reproduce Steps to reproduce the behavior:

1. Open a few tabs, in the middle a spreadsheet
2. Start from the left and press l repeatedly (or L per default I think) to go to the very last tab
3. It will (in most cases) go into insert mode over the spreadsheet

I think Google Spreadsheets might steal your input focus on something like the "tab switch" event. I would like an option to disable "input stealing on tab switching".

Browser and Vimium version Firefox 90.0.2

Same issue occurs on the Merriam-Webster website. Example:

0. Check Vimium option: Don't let pages steal the focus on load.
1. Open https://www.merriam-webster.com/dictionary/vim in a new tab.
2. The input focus is not stolen, as intended.
3. Switch to another tab.
4. Switch back to the Merriam-Webster tab. The input focus is stolen!

I think this is not a feature request, but rather a bug report.
