Pluto.jl: Pluto notebook freeze unexpectedly on warnings
One of my Pluto notebook freeze on warnings. It is not a fancy notebook, but it freezes quite often.
https://github.com/TensorBFS/TropicalTensors.jl/blob/master/notebooks/spinglass.jl
I notice that the if I remove the warnings. It does not freeze anymore. Maybe the warning is not handled properly! The warning is redirected to the browser console
Logging.js:21 ┌ Warn: Input type of `ArrayReg` is not Complex, got TropicalNumbers.CountingTropical{Float64}
handle_log @ Logging.js:21
2Logging.js:21 ┌ Warn: Input type of `ArrayReg` is not Complex, got TropicalNumbers.Tropical{Float64}
Also, wondering why can not I suppress the warning in a Pluto notebook with Suppressor?

The feature sounds good. But freezing after several warnings (like 10 warnings or so will trigger this bug) is an urgent bug because it is so hard to identify and so easy to depress users (I won't tell you I spent a whole afternoon to figure it out). Let me see if I can write some MWE to examplify this better.

I updated from Pluto 0.12.4 to 0.12.7 and ran into something similar. I ran my notebook, hit the following warning, and then it froze. Restarting Julia + Pluto didn't help (same thing happened). Reverted to 0.12.4 (glad I checked in the manifest!) and everything works fine, no warnings nor freezes.

Thank you @ericphanson! I also found the error you sent -- it will be fixed in #646

I've happily updated to 0.12.10 (which I understand includes #646) and have not had this issue again. @GiggleLiu maybe try that version?

Unfortunately, it does not fix my issue. In my case, there is no error information like you showed. I looks nornal in either the console or the Julia REPL, except the page is not reactive anymore.

I had Pluto froze in 0.12.10 while trying to install a package, and it never pases the "loading..." screen even in a new session. I think this is related to this issue.
Did you see any warnings in your REPL? In my case, it does not freeze anymore after I removed the warning statements.
