Mispplaced underling of grammar error when using Linbertinus Math spécials chars

[Pierre3888]

Hi, Not a problem of Libertinus font, but using this font whith LibreOffice or Apache OpenOffice is problematic

https://bugs.documentfoundation.org/show_bug.cgi?id=140935

this simple doc : de gain differential 𝐴𝐴𝐴𝐴𝐴𝐴𝐴 (𝑉ᵣ = 𝐴·𝑣H)et associate ?

Make LO find a real error (space before question mark) at the wrong place.

AOO crash when right-clicking on the underlined error

AOO with French Grammar checker Grammalecte crashes when opening the doc

So, using mathematical chars of Libertinus Math is quite problematic

I just wanted to inform you of this bug. And maybe someone can confirm it Pierre

I did a quick test and this happens with every font in LibreOffice. For U+FFFF and below, it's fine, for U+10000 and above, bugged. Right-clicking and correcting results in buggy behaviour, for example deleting the following character or converting it to an unprintable character. I'm quite positive that it is a LibreOffice bug, not a font bug.
