These are posts from 2017. There was indeed a time where the bad segments were not removed from the ICA computation. Now they are.
I added a note in the description of the ICA options to confirm this:

Time window: Time segment where the artifact is present.
Note that all the BAD segments are removed from the selected data before executing the ICA algorithm, causing some discontinuities in the signals.
