Search "f" broke in chrome on most sites (tags below page instead of on top of the page)

Describe the bug
Since today I've noticed that the "f" search doesn't work while using chrome on:

• Github
• Google

For the 2 sites above, the tags are visually below the page as seen in the screenshot/gif:

Although they still do work when pressed, you cannot see what letters you have to type for what link because the results are BELOW the page instead on top of it.

It does still work on the youtube homepage, but when I press "f" while watching a video it suddenly puts the youtube video in full screen mode instead of searching (never had this before? Not sure why the behavior changed)

To Reproduce
Steps to reproduce the behavior:

1. Type anything into google or visit ANY page on github.com and press F

Browser and Vimium version

Vimium Version 1.66

Side note - I've been using Vimium for at least 5 years every single day, never had issues until today. (just to show that the issue was never here and something changed to cause the issue)

Start by reproducing the link-hint behavior with Vimium 1.66 in Chrome 90 on Windows 10, using Google, GitHub, and a YouTube video as described. Inspect the link-hint rendering and the handling of the f key; done means hints remain visible in the page viewport and f does not unexpectedly trigger fullscreen on the reported sites.
