I'm using Chrome on Ubuntu 22.04.
The line generated by` \overline` is much too short. See the picture:
Maybe this bug is connected to T352609: native: \operatorname effect does not propagate into \widetilde arguments

I double-checked this, the resulting MathML is precisely as the MathML generated by MathJax. With both versions, the line is too short in Google chrome.
It is not clear if the correct utf-8 codepoint is used for overline. https://de.wikipedia.org/wiki/%C3%9Cberstrich
LaTeXML uses &175; which does not work in Chrome. Here, using &oline works, however. See https://github.com/brucemiller/LaTeXML/issues/2317
According to https://html.spec.whatwg.org/multipage/named-characters.html ‾ is U+203E
Change 1002609 had a related patch set uploaded (by Physikerwelt; author: Physikerwelt):

Change 1002609 merged by jenkins-bot:
[mediawiki/extensions/Math@master] Use U+203E for \overline macro
I think the bug exists again, see https://de.wikipedia.beta.wmflabs.org/wiki/Intbar#Widetilde_&_Overline
I use Ubuntu 24.04 and the latest Chrome version.
I tried to reproduce this with
Chromium 132.0.6815.0 (Developer Build) (arm64) Revision 0000000000000000000000000000000000000000-0000000000000000000000000000000000000000 OS macOS Version 15.1.1 (Build 24B91)
it generates the same output for MathML and native
<mover><mrow data-mjx-texclass="ORD"><mn>1</mn><mn>4</mn><mn>2</mn><mn>8</mn><mn>5</mn><mn>7</mn></mrow><mo>‾</mo></mover>
which looks as intended.
@Physikerwelt, the error is still present.
This is taken from https://de.wikipedia.beta.wmflabs.org/w/index.php?title=Intbar#Widetilde_&_Overline
Ok, I'll try with different computers. What happens if you zoom in and out? For me the line is flickering a bit.
Hi,
nothing will happen if I am zooming in or out. On my system there is also no flickering.
It looks just as wrong on my Android phone.
Works fine for me in Chrome.
Chrome Version 133.0.6943.142 (Official Build) (arm64)
MacOS 15.3.1 (24D70)
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?
I have an android device at home. Will try tonight.
Does
https://codepen.io/physikerwelt/pen/GgREKaq
render fine?
The codepen example looks okay
(The fraction doesn't look so good because the numerator is quite far away from the fraction bar. But this detail is not relevant here.)
