I tried the emulator as well, and if you pay close attention, you will notice a certain lag with this problem. Subsitute other limits, and the response is instantaneous. Go figure.

Using the physical Prime.

If you uncheck the Exact flag in CAS, you get the message:
Adaptive method failure, will try with Romberg, last approximation was 4.5

If you leave the flag set and hit "On" after starting the calculation you get 9/2 instantly.

In Home if you use the Template and input the integral, the calc hangs and pressing On results in
Error: Invalid input, but only if the CAS a Exact flag is set. With the flag clear you get 4.5.

Very strange
