Take this example:
<span lang="en" class="multilang">
<div>A test in English</div>
</span><span lang="fr" class="multilang">
<div>Un test in Francais</div>
This works in:
- courses pages;
- html blocks.
However it doesn't work (multilanguage spans are removed, hence all content is displayed independently from the current user lang) in:
- event descriptions;
- forum posts;
- footnotes in clean theme;
- ... (possibly in many other places).
If the div(s) are not present, the multilang spans are kept and the filter works.
My filling is that there is a filter function that all the possibly user-generated content pass trough, and this bug refers to such a function.
I have tested with <div> but there could be other tags that interfere with the language filter.
