It seems that constraint checks after adding a new statement only work when the “add value” feature was used to add another value to a statement that already existed when the page was loaded, but not on other new statements. The wbcheckconstraints API request is sent and receives a response, but nothing shows up on the page.
Probably some difference in the server-side- and client-side-generated HTML, I suspect.

| Correctly set element ID in statement group view | mediawiki/extensions/Wikibase | master | +9 -0 |
I suspect this is a regression in Wikibase – the reason that the gadget doesn’t attach the icon is that the surrounding statement group no longer has a proper ID:
<div class="listview-item wikibase-statementgroupview" id=""> ... </div>
If this were an intentional change, surely we would have removed the id attribute completely instead of setting it to the empty string? (An empty ID is not valid according to the W3C validator.)
I observed the same empty ID on the Wikibase Registry, which is running using @Addshore’s Docker setup in MediaWiki 1.30.0, so it seems this bug has been present for some time already…
Or is it possible that this simply never worked? jquery.wikibase.statementgroupview.js hasn’t seen much activity, and at a glance it looks like there simply might not be any code to update the ID.
