Exception on in-html Code Completion

Hi! Thanks for great plugin!
I got an exception when I try to use Javascript Code Completion inside regular html code.
Steps to reproduce:
Open html file with <script> tag
Type win and emit Code Completion (control + space by default)
Expected:
Code Completion appears
Actual:
Code Completion doesn't appears
IDE Error Occured message appears
java.lang.IllegalStateException: file.virtualFile must not be null
