XWIKI-21967: Dragging to resize the columns from Affected Children Live Data causes the page to be deleted without user's confirmation

[Sereza7]

Jira URL

https://jira.xwiki.org/browse/XWIKI-21967

Changes

Description

• Added a type to the dragNdrop buttons to avoid them accidentally submitting a form they were included in.

Screenshots & Video

After the PR changes, the resize and reorder handles have type="button". They don't submit the form the LiveData is included in anymore.

Executed Tests

Successfully built mvn clean install -f xwiki-platform-core/xwiki-platform-livedata/xwiki-platform-livedata-webjar -Pquality,integration-tests,docker.
After that, I included the JAR in my local distribution with ln -s -f ~/Documents/xwiki-platform/xwiki-platform-core/xwiki-platform-livedata/xwiki-platform-livedata-webjar/target/xwiki-platform-livedata-webjar-16.2.0-SNAPSHOT.jar xwiki-platform-livedata-webjar-16.2.0-SNAPSHOT.jar in the folder /webapps/xwiki/WEB-INF/lib.
With the updated code on my local distrib, I was able to test out the bug (that I previously made sure to reproduce on this distrib with the old code). I couldn't reproduce the unexpected behavior reported with the updated code, and the DOM changed as expected (see screenshot above).

Expected merging strategy

• Prefers squash: Yes
• Backport on branches:
  • None (same as XWIKI-21009: LiveData alternative to drag controls #2475, merged on master mid-january)
