I've updated the tentative election schedule to reflect the timeframe of the U4C vote, though further delays are possible depending on the progress of the U4C vote count. Also, from what I have seen, there is a rough consensus that an anonymous RFC can prevent ad hominem when discussing sensitive issues like the ArbCom, that it can run alongside normal discussions, and that the community should give the method a chance. Supposely the RFC will go ahead.

The problem is happening in Chinese Wikipedia. Mainly when saving pages, sometimes accessing pages. Some visual features (incl. the interface) sometimes cannot be rendered properly.
Update: From what I observe, the problem I face has relieved at the recent moment.

No. When I turn on the gadgets, turn off WikED, add something by using wikitext editor, then the problem can still be reproduced.

I just done it recently, it seems that no problems are there.

Hi @springrollconan, thanks for taking the time to report this!

Wondering if this is the same problem as reported in https://phabricator.wikimedia.org/T142137 - does it look like on the screenshot?

As the man-in-charge of TWA in Chinese Wikipedia, I can identify that the cause of the problem comes from https://zh.wikipedia.org/wiki/MediaWiki:Guidedtour-tour-twa1.js . A local sysop has this problem solved.
