Impossible to debug javascript freeze with devTools

Using devTools and adding logs everywhere didn’t help me debug a particular page.

I am working on a web component framework, and without going into the details or the way things work, I have my Chrome-based browser freezing during around 30 sec to 1 minute when I perform a particular action, and I can’t find any way to see where it is stuck. The same action in Firefox is immediate and has no consequence.

I have put a debugger just before the crash happens but it didn’t help.

Do anyone know a better way or wanna have a look ?

Just click the checkbox (it should change the number of the last entry of the list – called Chiara – at the bottom of the scroll).

Thanks!
