The issue seems to me as a possible regression of T174728: "Legend" retains some space if "Group results by change" is enabled - I will look into it.

German Wikipedia has a misaligned legend that overlays the other options.

There was the same issue in enwiki at some point. From the sceenshots I see that two variants of the Legend are present - one is with the links (and underscores) and another without links. I'll need to look into it too.

Those two issues in the task are closely related to
(1) overlaying results with 'Grouped by page' option

• T182156: RecentChanges legend overlaps actual RecentChanges was triaged and in RFP column of Collab-Team-This-Quarter

(2) misalagned/overflowing Legend

• T182363: [wmf.11] enwiki: Slightly misplaced Legend on Recent Changes/ Watchlist without new filters was filed about the same issue and it seemed that it was fixed in wmf.12. I checked the wikis (dewiki, frwiki) - seems to be fine:

I checked in Chrome and FF, full-screen, and also, as in the screenshot for German Wikipedia, I changed the UI language to English to see if it may push the Legend to overflow - did not see the issue. Additionally, I checked the Watchlist - no issue there either.

@Trizek-WMF unfortunately I do not have Chromium around... Can you verify that dewiki has the same problem as it was reported in the ticket? Also, do you have any custom CSS?

Same problem:

Also, do you have any custom CSS?

I've used safemode.

@Trizek-WMF yes, the issue with overlaying is present.

I thought that you have the issue with the Legend overflowing the fieldset:

I've confused my self with T182156: RecentChanges legend overlaps actual RecentChanges.

@Beta16: what is your browser, and which version?

Hi Trizek, I'm using Google Chrome version 63.0.3239.132 (64 bit).

As the description of this task says: with "Group results by page" active the result is this

I can confirm the problem in Mac Chrome.

The issue that you've confirmed it's #1 and seems to be a duplicate to T182156 (nobody argues that it exists).

I am more concerned about #2 which could be a possible regression, but I could not confirm it anywhere.
