Timed-out session allows false-feedback Save, Compile, Code operations #1699
Description
Scenario
I let my "apparent" session stay open for > 12 hours (with computer asleep). Woke up computer, cancelled out of the Save warning prompt and made code changes, then compiled, viewed code, then saved.
Problem
The Compile, Save, and Code buttons gave visual feedback that fooled me into thinking all was well, but it actually was not compiling at all, wasn't generating new code, and wasn't really saving either. I failed to recognize at first that no dialog appeared for Compile operation, but Code button indeed shows the code (but it's old code, previous to block changes made) and Save does the animated feedback expected (but didn't really save).
I didn't try downloading, so don't know how that responds; I realized something was wrong and refreshed my browser and was prompted to log in.
