Steps to reproduce:
I do some React development. I have written simple application to illustrate the problem that disturbs my workflow from time to time and urges me to move to Chromium/Chrome because Chrome does not have this problem.
Here is application that has intended problem:
https://rlq6mxr28q.codesandbox.io/
Press F12: no error is reported in console. Here is source code https://codesandbox.io/s/rlq6mxr28q, error is in actions/actions.js line 10. Error was made to illustrate the problem.
Actual results:
Nothing has happened. I made development error and I don't know about it anything. In this case as developer I'm lucky as I don't get result and this way I know that my code has problem. However sometimes I get error and I don't even get to know why that happens.
Expected results:
Error should be reported at least in console. E.g. if you opened my example code in Chromium you would get following error in console:
Uncaught (in promise) TypeError: Cannot read property 'toString' of undefined
at eval (actions.js? [sm]:10)
