I've been able to reproduce this behavior on a consistent basis now. It seems to stem from reinitiating form editing during a save operation.
The following scenario, usually produces the behavior.
For example. Say I have two form elements (fields). I edit the description of element 1 and save. Then immediately after hitting the save button & while the save operation continues I jump to element 2 and begin editing the description. The save operation will complete, but even though I am making changes to elements the save button will remain greyed out. It will not recognize any change from the save operation onwards. I must refresh the page to reset the behavior.
For now, I save often and try to remind myself to be patient with the save operation. Let it complete, take a breath then continue on editing the form. If save icon doesn't become active on my next change, I refresh the page.
