PythonRexExp lost highlight in pycharm

[trim21]

Describe the bug

regexp file have highlight, but inline code fragment re.compile('...') doesn't have highlight,

And I'm sure this string is consider as PythonRexExp, not plain text, because it has hightlight when I switch to monokai

in seprated editing view, it get highlight in the first place, then it become gray again

To Reproduce

1. install latest pycharm
2. install plugin
3. change Editor/Color Scheme to Material Darker
4. create a new python project
5. create a new python file (.py)
6. paste this as file content:

import re

pattern = re.compile(r"((?P<d>\d+)日)?((?P<h>\d+)時)?((?P<m>\d+)分)?")

Expected Behavior inline regexp should have highlight
