Description

I'm seeing an empty issue context popup that remains loading, when an external issue tracker is configured.
This is since upgrading from 1.14 to 1.15.

would it be possible to check the web console - there is likely to be an error in there.

OK it's likely something to do with:

gitea/web_src/js/features/contextpopup.js

Lines 5 to 12 in e2f0ab3

	export default function initContextPopups() {
	const refIssues = $('.ref-issue');
	if (!refIssues.length) return;
	refIssues.each(function () {
	const [index, _issues, repo, owner] = $(this).attr('href').replace(/[#?].*$/, '').split('/').reverse();
	const el = document.createElement('div');

this shouldn't be firing for external issues - so probably these need to have a different class instead of ref-issue or they need another tag.
