I'm using intellij 9. When I try to refactor > rename a CSS selector to a hyphenated one, Idea says that it is an invalid identifier (e.g. the CSS class "related-list"). I don't understand why since a hyphen is a valid character for CSS selector.
The ticket IDEA-34228 seems to be related to this problem but is marked as fixed and the limitation is still here for me.
Do you know this problem, and do you plan to fix it ?
