Unknown self-closing tags are auto-completed on </ in HTML

[FichteFoll]

Branched off from #78.

This works as expected for tags like <img /> but not for seemingly arbitrary tags.

Reproduction

Have the following text in an HTML file (or syntax):

<template>
<price />
<tag></tag>

When typing </ at the end it closes with </price>.

Expected behavior: Complete to </template>.

Surely the expected behavior from the example should be to close the template tag?

[FichteFoll]

Ah, yes. Edited.

It seems the way the close_tag command works is that it checks if the / before the > is scoped as punctuation.definition.tag.end.html - if it is, then it is skipped when finding the open tag that needs to be closed. So we can update the syntax definition to scope the / if it exists before the >.
