expressions 4 and 6 are rendered incorrectly in the lower native section. The upper MathML section is the intended result.

@Christian1985 the fix will be available on DE-wiki after December 12th. I was discussing with @Daniel_Mietchen sending out a signpost on the native rendering feature on de_wiki, do you think that would be adequate?

Hello @Physikerwelt ,

I think formula four and six are still rendered incorrectly. The "\nolimits" command in formular four ensures that the limits are not placed above and beyond the operator, but to the right of it.
And in formular six there is no \nolimits command, so the "limits" should be placed beyond the operator.

I think the new feature should only be advertised (via Signpost) when it is more stable. I have not activated the feature (in German Wikipedia) because it is not usable for me for example due to the font size (outlines) in Chrome. And I think some other bugs should also be fixed.

@Physikerwelt as author of WikiTexVC i would like to know of any signpost or publication activities, please let me know on any discussions and drafts.

In the ticket the MathML and native symbols look different, now they look the same

The discussion about signpost, might go to a different issue. At least there is a preprint on arxiv about the new rendering mode now.
