Fix wikitext preview in IE and Edge | mediawiki/extensions/VisualEditor | master | +1 -1 |
The issue is on Microsoft Edge 40.15063.0.0 on Windows 10 Pro Insider Edition (build 15063).
Error message:
SCRIPT438: Object doesn't support property or method 'forEach' ve.ui.MWSaveDialog.js (188,3)
body.querySelectorAll( 'link[rel="mw:PageProp/Category"]' ).forEach( function ( element ) { categories.push( ve.dm.MWCategoryMetaItem.static.toDataElement( [ element ] ).attributes.category ); } );

Has the change been merged into the English Wikipedia, as I am still having the problem there?
Not yet, the fix is merged into the beta cluster. It will be released as part of 1.30.0-wmf.10 on English Wikipedia on Thursday, July 20. You can check https://www.mediawiki.org/wiki/MediaWiki_1.30/Roadmap#10 for the schedule.
I have an install of IE11 on Windows 7 at work and I am still seeing the hanging behavior today on en.WP (wmf10 was merged as expected) even after clearing my cache and doing a hard refresh.
It looks like I don't have access to console either else I would try to get a snapshot out of there (group policy? dumb....).
I see that too on Windows 10. That's IE11 only, Edge works fine. I filed another task since it seems like a separate problem: T171600: Show preview stopped working in IE 11.
