User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:109.0) Gecko/20100101 Firefox/119.0

Steps to reproduce:

  1. Open this gist:
    https://gistpreview.github.io/?0b031ea78c629bc5df46ac02b8199bf7
    https://gist.github.com/FeBe95/0b031ea78c629bc5df46ac02b8199bf7

  2. Scroll to the end of the page

  3. Focus first input

  4. Press Shift + Tab ⭾

Actual results:

Page scrolls up a bit

Expected results:

Page should not scroll at all

The bug is mainly caused by a very small CSS 'scale' value in combination with the input being positioned near the top. You can play around with the scale value of the input and the padding value of the navbar.

A real-world example has 'scale(0)' on a hidden input element, which is used for a select box in the frontend.

I'd wait for landing bug 1858984.

Looks like bug 1858984 is now fixed (in Firefox 123, which was released a few days ago).

Felix, could you confirm that the issue is resolved for you in Firefox 123?
