Description

Thank you for the great work on this VectorGrid!

It works fine in Webkit based browsers and Edge. However, when I was testing it in IE 11, it was crashing on: https://github.com/Leaflet/Leaflet.VectorGrid/blob/master/src/Leaflet.VectorGrid.Slicer.js#L33

I'd not take any actions yet to debug / rewrite this part of code. Is anyone seeing the same issue ?

Research direction

Start with src/Leaflet.VectorGrid.Slicer.js at line 33 and reproduce the Worker syntax failure in IE11, comparing it with the working WebKit and Edge behavior. The issue is complete when the Worker code loads without crashing in IE11 and the affected behavior is verified.
