I have a problem with Docs regarding Latex, and I would like to share this with you.
When I am about to enter a mathematical formula in a new and empty mathematical block, the software starts to bug.

I don’t know if you’ve been warned about this, but just in case, I’m warning you.

It is this one : ONLYOFFICE Desktop Editors version 7.3.0.184 (x86 exe)

It is mainly when there is the small square in the Latex area and not the text explaining you can enter the formula. Then I can’t modify to put any formula or there is an error.

I also have the same problem at the moment with this formula : \int_{_0}^{2\pi}\int_0^R \left(\matrix{kr\sin{\left(\theta \right)}\\z\cos{\left(\theta \right)}\\(\sin^2{\left(\theta \right)}) \over (1+r^2)}\right) \cdot \left(\begin{matrix} 0 \\ 0 \\ 1 \end{matrix} \right) \mathrm{d} S

OnlyOffice is frozen, and I need to close and reopen it. Then the formula is still not changed to be readable.
