**Steps to replicate the issue** (include links if applicable):
* With latest Vector go to the Special:RecentChanges
* Collapse the sidebar
**What happens?**:
You'll notice that the content container (`.mw-content-container`) does not expand to fit the empty space. See image below:
{F35468959 width=900}
**What should have happened instead?**:
The content container should have expanded to fill the empty space.
| {F35469880 width=500} | {F35469882 width=500}

**Software version** (skip for WMF-hosted wikis like Wikipedia):
Vector 2022 master
**Other information** (browser name/version, screenshots, etc.):
Looks like it was caused due to: 814921: Allow composer/installers plugin | https://gerrit.wikimedia.org/r/c/mediawiki/skins/Vector/+/814921 when the `.vector-layout-grid` class was removed.
The related style also no longer applies:
```
lang=css
.skin-vector-disable-max-width .vector-layout-grid .mw-content-container {
max-width: none;
width: 100%;
}
```
