According to my study of one billion Web pages, less than 0.0013% of pages use the <isindex> element. In fact, so few pages use it that it didn't appear on my top 1000 most-used elements list, meaning it was used less than <side_ads>, <preform>, <titolo>, <bdbereich>, <org>, <cunet>, <l1>, <hot:trolley>, and numerous other bogus elements.
<isindex> has been a pain (see e.g. bug 4574 or bug 4828), and Safari's support for it differs from Mozilla's, IE's, and Opera's.
I would like to drop support for parsing <isindex> specially in HTML5. If it turns out that <isindex> _is_ in fact used, then we'll find out about it soon and can change the HTML5 spec so that it is clear how it should be implemented.
HTML5 was changed by the way to support <isindex> in the parser.

So shouldn't the bug to be resolved as WONTFIX?

And Bug 18415.
Since we last looked at this, Chrome and IE have both said they will drop support for this tag.
Blink thread: https://groups.google.com/a/chromium.org/forum/#!topic/blink-dev/14q_I06gwg8
I can't find a citation for isindex being dropped in Project Spartan, but Travis from MSFT confirmed this in a conversation.
Right now we're at 2 vs. 2 rendering engines with regard to isindex support. Is WebKit interested in following along and removing it? https://github.com/whatwg/html/issues/1088
It has been removed from the spec.
Tests added to web-platform-tests in
and html5lib-tests in
Given that this was dropped from the HTML spec, Chrome and Edge, I think we should at least try to drop <isindex>.
