Autosaving contexts

Very often (particularly when I commit to my VCS) PHPStorm will automatically create a new context.  Is there any way to turn off that automatic generation?  I use contexts but I use them intentionally.  I want to save a group of tabs for later reference.  But because PHPStorm automatically creates them I have to wade through the chaff to get to what I need and I would rather it didn't.

I looked through all the settings but I couldn't find a way to disable this behavior.  Is there a way I can?

thnx,
Christoph
