v2026.2.0-latest +1 seems to have introduced (at least for my installs) that mobile rendering only shows threads and content on half (left half) of the screen when foldable is “wide”
Header, footer, and column headers (“topic replies, views activity”) are all full width
Tested across 2 sites, same results. Not an issue here on meta.
Same issue if loaded while folded or unfolded
MAY NOT have been 2026.2.0, I only update once a week
