VE allows to mark text as both superscripted and subscripted (<sup><sub>text</sub></sup> or the other way). That sounds like a bad idea; such text simply ends up being displayed in smaller font.
I don't see how this is a bug? Yes, it's bad, in the same way that setting text's colour to be white, or putting an image inside another image's caption, but that doesn't mean we should stop people doing it… Generally, appropriate use of the software is a social thing, not a software thing. Willing to be convinced otherwise, but for now I'll mark this as a WONTFIX.
Do other text editors permit that? I don't know of any that would.
(Or in other words, this is not fitting users' expectations.)

As input, sure. But as output, HTML lets you do lots of things that VE doesn't.

A dupe was just filed, this is not just me. Reopening.
Wikitext lets you do this too. Do you think we should just silently kill all examples of this in the database? :-) Closing again unless you can suggest (a) what should happen in VE when the user attempts this, (b) what should happen in VE when the page already has this, and (c) what should be changed in MediaWiki's PST to stop this happening in future(?).
(In reply to James Forrester from comment #8) > (a) what should happen in VE when the user attempts this Text should be either super- or subscripted, not both. Nesting superscripts in subscripts, subscripts in superscripts, subscripts in subscripts and superscripts in superscripts should be impossible, just like it's impossible to nest links in other links. Currently only the last two are impossible. > (b) what should happen in VE when the page already has this The same thing that happens with all other unsupported input: it should be alienated and left alone. > (c) what should be changed in MediaWiki's PST to stop this happening > in future(?). Nothing. I suppose there are very rare use cases where this could be wanted, we should just keep supporting them for backwards-compatibility. In fact, the only things that I see in existing articles are currently impossible in VE – you can't nest superscripts to produce, say, 10<sup>10<sup>26</sup></sup> (10^{10^26}) used in [[pl:Oś czasu dalekiej przyszłości]]. Arguably this should just use <math/> tags though.
I agree that the sub/superscript tool should clear any other sub/superscript annotations present. As pointed out you can't do a double superscript, so clearly our goal is not to let you create any complex hierarchy you want, that's for <math>. I don't think we need to alienate such nested content though, in the same way we don't alienate a double bold tag (if someone used one). As long as the user doesn't try to change the sub/superscripting, the annotations will remain untouched.

Currently only the last two are impossible. This works for me. Re-wording bug for clarity – is this acceptable to you?
Yeah, that's what I meant. Thanks.

This is happening again, the superscript and subscript both are getting applied at the same time.
I can't reproduce. Steps?

Let's leave the bug as fixed in the original fix, not the recent minor breakage.
