[12:19:32] <physikerwelt>	 edsanders, I implemented a wikibase entity selector for math following your ooui tilte selector. While it works, I did not really get the point with the empty abort object promise. Maybe you can have a look at https://gerrit.wikimedia.org/r/c/mediawiki/extensions/Math/+/638094?
[13:04:51] <edsanders>	 I think in a few places we assume that the promise object is a jqXHR object, which is abortable
[13:05:59] <edsanders>	 mw.Api objects have an abort method by default though
[13:06:23] <edsanders>	 so I think in this case you do need to set one
