"CTRL+ Mouse Click" with a CSS class-name is not working in VS code

[Oneway2live]

version: 2.0.14

I got this issue when I used the "CTRL + Mouse Click" operation with a CSS class-name.
In usual,the editor should show the definition and go to it. Like:

but now it's not working. When I pressed the CTRL button and hovered on the class-name it showed nothing, and when I clicked the class-name,I can't go to the definition too. Like:

Not all of the vue file got this problem, it occured in some of it but I cannot figured it out.

Is it the bug of Vue Official or my configuration is wrong in some places ?

Wishing somebody can answer and help me to find the reason.
