Reported from OTRS - https://ticket.wikimedia.org/otrs/index.pl?Action=AgentTicketZoom;TicketID=11026281
User reports - When using Russian or Ukrainian language (maybe some others too) the temperature or catalyst can't be viewed (in attachment you can see what I mean; although you can see temperature, but it can be interpreted as 100 °C or 180 °C, when the right one is 160 °C)
Note - I am working on finding the specific article to test against with other languages.

Is this also about formulas being cut off at the right?
I am working on finding the specific article to test against with other languages.
That's https://ru.wikipedia.org/wiki/Ацетат_кальция#Применение
It looks like the content service (or Parsoid?) is adding an artificial margin-top to the image that contains the chemical formula, which is causing the topmost text to be clipped.
https://ru.wikipedia.org/api/rest_v1/page/mobile-html/Ацетат_кальция
This margin is not present in the same page in mobile web.
Not sure where the style attribute in the following HTML snippet is originally coming from but it's also in upstream Parsoid output, which is used to build the mobile-sections and mobile-html outputs. It's even in the Desktop output.
<img src="https://wikimedia.org/api/rest_v1/media/math/render/svg/7225efe5e8fc4e48d91691e0a307b8e2b915c725" class="mwe-math-fallback-image-inline" aria-hidden="true" style="vertical-align: -0.838ex; margin-top: -0.425ex; width:40.169ex; height:4.343ex;">
I suspect this is coming somehow from the Math extension or Mathoid.
The mobile web output does't have vertical-align: -0.838ex; margin-top: -0.425ex; in the inline style attribute on these image tags. Also not sure why.
Maybe @Physikerwelt has an idea why the margin-top exists; or @Jdlrobson how it gets removed from the mobile web output but not in other places?
@Jdlrobson That's good to know. So mobile web would be broken, too, once T207929 is fixed.
I looked at the Parsoid html and math element - the problem is with a little bit less height of the formula image. Looks like it can be fixed in Mathoid.
