MathML rendering appears to be broken in FF 43.0 for Mint
Pages displaying MathML (including Mozilla's own MathML Torture test https://developer.mozilla.org/en-US/docs/Mozilla/MathML_Project/MathML_Torture_Test) now display greatly exaggerated inter-line spacing.

Disabling the Latin Modern Math font fixed the problem.

Hi
I have tried loading https://developer.mozilla.org/en-US/docs/Mozilla/MathML_Project/MathML_Torture_Test in my copy of Firefox (45.0a2 (2016-01-24)) and it appears without any issues.
Please can you append a screenshot with what you are seeing as that may help us to find a solution for you.
Single-line Torture test items look fine, but multi-line displays are spread out. This makes MathML proofs impractical to read.
I've attached a screenshot showing how item 18 of the Torture test is incorrectly rendered.
My version of FF updated this morning; the problem persists with version 43.0.4
Looks fine here on Linux.
Did you try to use the inspector to see what is causing this?

@co-el I'm running Linux Mint.
The inspector tells me that in my own example and in item 18 of the Torture Test page, the height of the box of math elements suddenly leaps up to 104/106 px. Nothing relevant shows up when I inspect css rules.
Just to clarify: the first 17 Torture Test items look fine. Things go wrong for me at item 18, as shown in my earlier screenshot.
Item 18 is the first one where more than one line of MathML is displayed.
I just upgraded Mint to Rosa (17.3) but the problem persists.
