211 build broke plugins and throws "dataContext has no component for new ListPopupStep"

Both my plugin (gitflow4idea) and several others have encountered this issue in the new 211 build when creating a new

PopupFactoryImpl.ActionGroupPopup

Example 1
https://github.com/Haehnchen/idea-php-symfony2-plugin/issues/1614

Example 2
https://youtrack.jetbrains.com/issue/CWM-1892

Example 3
https://youtrack.jetbrains.com/issue/IDEA-262024

Example 4 (gitflow4idea):
https://pastebin.com/9hCd3vgE

The code that prompts this looks in all cases something like this:

new PopupFactoryImpl.ActionGroupPopup("Gitflow Actions", popupGroup.getActionGroup(), SimpleDataContext.getProjectContext(project), false, false, false, true, null, -1,

And  the exact culprit is this:

SimpleDataContext.getProjectContext(project)

Is this a bug or did something change in IDEA? Or is there some other way now that we should be calling this function?
