Christian1985 added a comment to T385948: Native MathMl - Prime not rendered correctly.

in your screenshot, the prime symbol looks exactly like in my screenshot. However, I am not convinced that this is correct. In my opinion, the prime symbol should start a good bit further down. The prime symbol should start at the crossbar of the f and only reach to the top of the f. Especially with letters like 'a' or 'm', you don't see any spatial relationship between the prime symbol and the letter.

That is strange.
I have now tested it again in Chrome (Version 134.0.6998.35 (Offizieller Build) (64-Bit)) on Ubuntu in incognito mode. It still looks like in the screenshot.
Are any of you able to test the example with a Chrome on Android?

However, if you allow the CD environment in the Math pseudo-tag environment, then you have to think about whether the diagram is displayed correctly as SVG, using native MathMl and with MathJax. If you would introduce a new pseudo tag, you could concentrate on one technology. Of course, this has other disadvantages.

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.

Christian1985 added a comment to T137787: Add integral symbol with short horizontal bar in the middle (⨍,⨎).

Hello @Physikerwelt
I think intbar corresponds to Unicode U+2A0D and is correctly represented in the PDF. The strokedint corresponds to the Unicode character U+2A0F. According to the German Wikipedia, the Unicode character is also called "integral average with slash". However, the mathematician and author Evans uses the Unicode character U+2A0D for the average integral in his books. I find that somewhat irritating.
