[Icons]: HTML syntax: Closing the tag with </twig:ux:icon> breaks it

[ThomasLandauer]

When doing (as mentioned at https://symfony.com/bundles/ux-icons/current/index.html#twigcomponent )

<twig:ux:icon name="user-profile" class="w-4 h-4">🧸</twig:ux:icon>

I'm getting:

An exception has been thrown during the rendering of a template ("Unknown component "ux:icon". Did you mean this: "UX:Icon"?")

So it looks like only the self-closing syntax is allowed:

<twig:ux:icon name="user-profile" class="w-4 h-4" />

Versions:
Brandnew Symfony 7.3
symfony/ux-icons 2.25.0
symfony/ux-twig-component 2.25.2
twig/twig 3.21.1

P.S.: So the misleading hint for UX:Icon which you mention at #2307 (comment) is still there.

So it looks like only the self-closing syntax is allowed:

It is, and won't change.

It was working initially "by chance". The current behaviour (since 2.21) has not raised any real world problems. On the other hand, beeing more strict about this helped improve preformance big time.

So this is not something that will change now, or in the near future.

If you have time / want to open a PR to improve this part of the documentation, it would be very welcomed 😄

I added a note at #2789 (comment) to remember it :-)
So I'm closing here as "not planned".
