The reason is simple. The primer has the potential to seep under the tape and soften the glue leading to more extensive seeping. Electrical tape is not designed to withstand some chemical exposure.
Go to a specialty auto paint store and buy the best tape you can buy for masking. 3 M Fine Line comes to mind. It is expensive as far as tape goes but cheap in comparison to the cost of your canopy.
I have done the back glass of my tip up and helped two others do their entire canopy. I used 3M tape and one of the other guys used it as well. The lines were crisp and clean with no sign of bleeding. The guy who didn't use 3M had evidence of bleeding and a few areas of greater seeping.
The appropriate tape to do an entire canopy will probably run you $40 as compared to less than $10 for cheap electrical tape. Definitely not the place to save money.

Scotch Super 33+ (surprise!) electrical tape withstands Sika 209 & 206 primer, in my experience. I used a bunch of it to mask for my windscreen installation last month; it pulled away cleanly with crisp lines. No evidence of bleeding under, either on the acrylic or aluminum. It's twice as expensive as the no-brand stuff but, as with the masking tape, it behaves much better in exchange for the higher cost.
