Subject: Avoid blinking change tracking cur for math inset.
X-Git-Tag: lyx-2.4.0dev-acb2ca7b~1341
X-Git-Url: https://git.lyx.org/gitweb/?a=commitdiff_plain;h=bf7f4d716cf0ef148495d7ecd616a1aaea57a13d;p=features.git

Avoid blinking change tracking cur for math inset.

Since there is a margin above and below the inset, there is no problem
for putting it higher.

Fixes bug #11684.
