Attached image What should happen.

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:109.0) Gecko/20100101 Firefox/118.0

Steps to reproduce:

Use Bootstrap 5.3 (this probably doesn't matter)
Set this/a similar rule in the CSS structure:
box-shadow: 0 5pt 0 black

Actual results:

The shadow has an annoying offset that gives it a little gap.

Expected results:

The results on Chromium, WebKit or other engines. (Regular-CSS.png)

Btw, the image there is what is rendered on Google Chrome (what SHOULD be rendered.)
