CX2 translation view: JQMIGRATE: jQuery.fn.offset() requires an element connected to a document
Closed, ResolvedPublic

Description

New warning in the JS console. This looks like something that will break when JQMIGRATE is taken away. Introduced in https://gerrit.wikimedia.org/g/mediawiki/extensions/ContentTranslation/+/74da638516df477d764fa95d4ed968fd147cd77e

Nikerabbit moved this task from Maintenance backlog to QA on the Language-2018-Jan-Mar board.

Looks like either a change in VE or CX has fixed this. Not surprising given the changes to the toolbar code.

Seeing this again, but from a different source now, related to alignSectionPairs.

T177252: JQMIGRATE warning "jQuery.fn.offset() requires an element connected to a document" when the element is the root had similar problem and see the discussion.

Following patch can replace the offset() call with native getBoundingClientRect and avoid the warning.

In this case I doubt it is about the htmlelement (and if it were I believe the fix would be different). It is nice that JQMIGRATE gives the warning, because for unattached elements we just get zeroes which is not what we want either:

$( '<div>' )[0].getBoundingClientRect()
{x: 0, y: 0, width: 0, height: 0, top: 0, …}

Could there be a race condition where alignSectionPairs is called before restoration is complete? There are many callers of this method so it is hard to check, and I cannot reliably reproduce it.

Actually I can, I just need to change the target title of the page from the default one to trigger this. I'm proposing an alternative fix.
