Hello, As discussed in a previous meeting the DisplayOperatorMinHeight does not seem enough to get the proper size of large operators in display style. At least WebKit, Gecko and XeTeX implementations had to perform heuristics to work around issues with existing math fonts. In the past, something similar was in the MathML Core specification but was removed until we get clarification from Microsoft about the correct way to interpret DisplayOperatorMinHeight. Now that MathML is shipped in Chrome, Edge, Opera, etc (all of them implementing DisplayOperatorMinHeight as per current version of MathML Core, without extra heuristics) this known issue showed up again, even with Microsoft's own Cambria Math font: https://bugs.chromium.org/p/chromium/issues/detail?id=1408038 Two weeks ago I tried to summarize the status and observation on the dedicated spec issue: https://github.com/w3c/mathml-core/issues/126#issuecomment-1425804878 I'd really appreciate feedback from Microsoft on this, so we can progress on the spec issue and decide how to fix the chromium bug! Thanks, PS: As a completely unrelated issue, https://github.com/w3c/mathml-core/issues/121#issuecomment-1082761758 has also remained unanswered for a while. -- Frédéric Wang
