"Invalid HTML" - but accepted in editor!

[Andrew Neil]

See:

The post editor allows me to create multi-level subscripts, and it displays fine in the editor:

But, when I post, I get the "Invalid HTML" error, and the post loses all the subscripting:

Is this intended behaviour?

To be able to subscript would be useful.

PS:

So the HTML is not invalid; it may be unsupported - but it's not invalid.

Thanks for reporting back, even though it was not the desired result.
I'll do some additional testing and be in touch soon.

Testing again:

It still gets rejected:

In the HTML editor:

OK in the composition/preview:

Rejected on posting:

And again:

^super normal _sub

That seems to have worked!

@Laurids_PETERSEN  I have un-marked the solution, because this has broken again!

super normal sub

That works in the editor, while composing the message:

But when I hit the button to post, it's again giving the "invalid HTML" - and removes the sub/superscript:

PS:

Maybe pure coincidence, but the  'Related Content' pointing to the *same* thread!  issue has also returned.

Hi @Andrew Neil 

Thanks for letting me know. I'll investigate and ask for a fix asap.
