Progress bar disappears before microflow executed completely

Hi, I am using Bootstrap Multi Select widget in that I have called on change microflow, where I have enabled show progress bar. The problem here is progress bar disappears before the microflow executed completely. Microflow takes around 1 or 2 minutes to complete but progress bar is appearing for only 10 seconds.   Any idea to increase progress bar timing would be appreciated. Thanks.

i believe this is not something you can fix without modifying the widget itself, but i may be wrong.

I would create an issue in the github repo, it might get fixed by the developer: 

It is a community supported component though, so there is no guarantee it will get fixed.
