Reportable bugs on UCP

Issues that have only arose after UCP roll out:
 * Replying to comments results in an error, luckily still posts (may occur by replying to your own comment) Resolved
 * Recent changes module doesn't list changes by page but per change, two back-to-back edits lists the page twice File:Bug on Recent Wiki Activity module.png
 * Default templates added to new wikis are no longer compatible with UCP (e.g, Hatnote) File:Using default template results in script error.png

Not quite bugs but definitely overlooked:


 * Upload dialog is fixed, this impedes on License drop down
 * Thumbnail images on edit preview appear like MediaWiki's File:Bug on preview for thumbnail images.png
 * Contributions (Special:Contributions/WEEABXTCH) has 0 margin (simple change to .mw-contributions-list can fix this) File:Margin issue on Contributions.png
