XWIKI-12646: Page name out of bound for Document Tree, Activity Stream, Space Index and on Children viewer

Changes

Description

• Added a couple style rules to make sure the Activity Stream and Pages widgets behave when there's unexpectedly long page names.

Clarifications

• There might be alternative compromises, but this one works well IMO.
  • We want all gadget content to not overflow their space. This stops page names from overflowing but also prevents other unexpected situations that might arise depending on the gadget. This is the equivalent of what was done for panels.
  • The notification box has a overflow-wrap policy that will break large words if needed. https://developer.mozilla.org/en-US/docs/Web/CSS/overflow-wrap#break-word

Screenshots & Video

Here is a screenshot of my dashboard after applying the styles. We can see that on all the elements, a page with a very long title (both regular word-length and one very long word in it) is displayed somewhat successfully.

Executed Tests

Style changes only, I only performed manual tests on my local instance. Given the content of the changes, I don't expect any possible regression.

Expected merging strategy

• Prefers squash: Yes
• Backport on branches:
  • N/A, small bug fix.
