If you use a quality factory made heat shrink connector this will almost never happen. I've used perhaps thousands of these factory made heat shrink connectors at this point and I always inspect them after the termination is made and I've yet to see more than a very low percentage perhaps .2% had the gap or point of entry you describe.
The heat shrink material that comes on the factory made terminals is much thicker and far more robust than the adhesive lined heat shrink you can buy off the shelf.
Notice the glue oozing out of the ring end of that terminal.
