The REAME on a repositories home page is 2px wider than the other elements in the main container. 1px on each side.
There appear to be at least 330 files that have one of these styles, I have tried to go through the UI and look for any regressions, but I may have missed some.
```sh
rg '(?=.*\bui\b)(?=.*\battached\b)(?=.*\bheader\b)' --pcre2|wc
275
rg '(?=.*\bui\b)(?=.*\battached\b)(?=.*\bsegment\b)' --pcre2|wc
330
rg '(?=.*\bui\b)(?=.*\battached\b)(?=.*\btable\b)' --pcre2|wc
56
```
I tried to track down the origin. I found the following information.
The behavior originates in semantic-ui, and was carried on in the fomantic-ui fork. It looks like the author was trying to achieve a 1px box-shadow look, but decided to implement it using a border after poor results with box-shadow.
* attachedHorizontalOffset introduced, a623e4411c
* attachedHorizontalOffset used for the margin on `.ui.segment.attached`, 5c7d5f13d8 (diff-ce37074faff5ddf9591ee8fd88818b6e99376519ce9e6e451cdb7db20dcbecf6R449)
I also found some upstream issues raised about the same bug:

This is a very old bug with the bottom border-radiuses not being there
and the `:has` selector now makes it possible to cleanly solve it. It
affects all header+segment boxes, which there are many throughout the
UI:
