Steps to reproduce

Here my original input text is a LaTex formula surrounded with \[ ... \] , but after it goes into the remark tree, the slash at the beginning is gone. Another slash before the last square is also gone.
Then it is not going to identify LaTex formula correctly with the pattern \[ ... \]
Please see the screenshot, I have console.log the input text, and the remark tree nodes.

Expected behavior

The slashes should be kept.

Actual behavior

The slashes are gone
