Basically, they had an HTML
<button> that when clicked would
display:block a descendent
<dialog> element that contained some hyperlinks to help you create a new project.
The simplest test case:
<button> <a href="https://example.com">do cool thing</a> </button>
Problem is, clicking on an anchor with an
href inside of a button does nothing in Firefox (and Opera Presto, which only 90s kids remember).
What the frig, web browsers.
<a href> is totally, like, interactive content, itsho*)
Soooo, probably not a good idea to follow this pattern. And who knows what it means for accessibility.
The fix for glitch is simple: just make the
<dialog> a sibling, and hide and show it the same way.
