Which actions are these? We would need a list of problems OR try to find them ourselves, but that might not surface the relevant ones since we are no frequent editors of Lexeme.

@Jan_Dittrich to name one: when new area if opened (new/edit Form, new/edit Sense/Gloss) then always focus first field in opened area. Now focus is placed nowhere. See screenshot in https://phabricator.wikimedia.org/T197594

There's also no field focused when editing the lemma.

In case it's useful to anyone else, I cobbled together the following bit of code last night and put it in my common.js:

mw.hook('wikibase.entityPage.entityView.rendered').add(function () {
	/* focus lexeme form when editing */
	$(".wikibase-lexeme-form .wikibase-toolbar-button-edit a").each(function() {
		var id = $(this).parents(".wikibase-lexeme-form").attr("id");
		$(this).on("click", function() {
			setTimeout(function() {
				$("#"+id).find(".representation-widget_representation-value-input").eq(0).trigger("focus");
			}, 500);
		});
	});

	/* focus lexeme lemma when editing */
	$(".lemma-widget_edit").on("click", function() {
		setTimeout(function() {
			$(".lemma-widget_lemma-value-input").eq(0).trigger("focus");
		}, 500);
	});
});

It only works for editing lemmas and existing forms, since that's all what I was trying to edit at the time.

One issue that still exists is that all the statements of a Sense or Form come before the “edit” button for the glosses or form representations in the tab order. So if you tab through Beta’s L1, for example, you’ll first get the two “jump to” navigation links, then the lemmas link (so far so good), then the language and lexical category, then the Lexeme statements (good), then the Sense statements (skipping over the Sense “edit” link) until the Sense “add statements” link, then jump back up to the Sense “edit” link, then jump down to the second Sense’s statements, go through those statements until “add statement”, then back up to the second Sense’s “edit” link, and so on. This jumping around is fairly confusing.

More issues:

Clicking "edit" for the lemma focuses the lemma field, but clicking the buttons to add or remove spelling variants doesn't put the focus back in a field. For add, I would expect the focus in the lemma field of the new spelling variant. For remove I think it would make sense to put the focus in the lemma field of the previous spelling variant if the one you're removing is not the first or the new first one if it is.

I can't tab to them at all because they're not buttons and don't have a tabindex attribute - T250519
