Looks good!
However, this doesn't seem to have fixed the issue VIPEROMCT-345 completely. (Admittedly I tested this on Firefox)
Open MCT froze on and off while trying to complete the large import. That said, the browser did not crash.
If this is the desired outcome, then we should merge this.

Apparently the freezing is a different issue that's being fixed elsewhere. The error mentioned in the linked issue is no longer visible, so I'm merging this.
