I'm getting a weird issue when I hover my mouse pointer over MathJax / Latex with "cases":

$$\text{HMAC}(K, m) = \text{H}((K' \oplus \mathbb{opad}) || \text{H}((K' \oplus \mathbb{ipad}) || m))\\K' = \begin{cases} \text{H}(K) & \text{if } K \text{ is larger than block size} \\ K & \text{otherwise} \end{cases}$$

Normal look:

When hoovering:

This is on Windows 11 / Edge Version 132.0.2957.140 (Official build) (64-bit)

Does anybody know why this is happening?

  • $\begingroup$ It's not clear whether you are complaining about the fact that there is a magnified version of the math at all, or that the window for it is too small. if the former, it is there because you have the "Zoom Triiger" set to "Hover" in the MathJax contextual menu's "Math Settings" sub menu. If it is the latter, the width may be restricted by the size of the container element holding the math, but the height shouldn't be. Perhaps that is CSS in the page that is affecting the MathJax output. $\endgroup$ Commented Feb 13 at 11:09

    $\begingroup$ Could you include the rendered MathJax directly in the post so that anyone else can try and see how it looks? (cannot suggest an edit on meta) $\endgroup$ Commented Feb 14 at 6:11
  • $\begingroup$ @DavideCervone I am using Microsoft Edge for Android (136.0.3240.91) and as implemented here MathJax doesn't offer a "Hover" option in the "Zoom Trigger". Maarten, I can not repo on Android. See screenshot. $\endgroup$ Commented May 30 at 13:16

    $\begingroup$ @Rob, your screenshot shows MathJax v3, so you must have selected that in your profile preferences. The hover option was dropped in v3, as it was an awkward feature. Maarten is still using the default v2 implementation, which has the hover option. $\endgroup$ Commented May 31 at 23:58
  • $\begingroup$ @DavideCervone Thanks for your expertise. Repo'd - Microsoft Edge for Android (136.0.3240.91). $\endgroup$ Commented Jun 1 at 3:18
