Styles disappear after insert is applied

[poincare15]

Step - 1: Write anything
Step - 2: Apply a style (color, background etc.)
Step - 3: Select the text.
Step - 4: Apply insert (sqrt, frac etc.)

Your applied styles disappear (colors, background, size, \displaystyle etc. removed)

Is this a bug?

A detail worth adding: this happens if you select from right to left. If you select from left to right, you get the expected result.

Interestingly I got the same error in bug two directions. I think I'm doing something wrong.

My solution:
replace 'latex-unstyled' with 'latex'

mathlive/src/editor-mathfield/mode-editor-math.ts

Line 217 in 7860e50

: model.getValue(model.selection, 'latex-unstyled');

I solved it this way. I hope I didn't break anything else.

That seems to be a different problem. I don't think this code path is used when following the steps in this bug report (i.e. selecting a subexpression, then typing something on the keyboard to replace it). It may be that using latex instead of latex-unstyled might be OK. I'll need to think about it.
