How to highlight a class like fbck-ttl?

Question

webstorm

Hello everyone, please tell me, I have a webstorm version, if it is important, 2018.1.4. There was such a problem, we made a standard for class design:
removing vowels and the "-" symbol, as an example: fbck-ttl or lft-txt. Of such kind.
The problem is this:
on double-clicking, such a class is not completely selected (triple-clicking selects the entire line and this is not an option).
How can I set the selection of the entire word by double LMB if this word is written with a dash?
Upd.:
In HTML&CSS double click selects normally, but how to do it in other files like *.pug? I tried to open it as html, unfortunately I lost the syntax highlighting and the selection still does not work.
