How to remove custom HTML attributes and tags?

Question

phpstorm

I once added a custom attribute to an html tag and memorized it in the IDE. <br custom-attr="test"/>
It was the same with the custom tag. <cusom>
And now auto-completion constantly drives mixinclass or realhtml tag customhtml tag instead of class.
Where can I find them in the settings to remove them?
