Sequences don't allow repeated characters

[littletinyfish]

I'm trying to create a sequence that quickly renders Unicode characters. Since the KLL/USB spec doesn't allow Unicode, I've set up sequences for the ones I use most often.

For instance I've assigned Layer 3 > Key C to the sequence 0169. When I hold fn3+Alt and hit C it gives me ©.

#Configurator code:
U"C" : U"P0" , U"P1" , U"P6" , U"P9";  # Copyright.

However, certain alt codes require repeated characters, which do not seem to register. The horizontal ellipsis, for instance:

#Configurator code:
U"X" : U"P0" , U"P1" , U"P3" , U"P3";  # Horizontal Ellipsis
U"X" : U"P0" , U"P1" , U"P3" , U[91];  # Tried faking it by using a different format key code.

When this sequence runs, it should output 0133. Instead, it outputs 013.

These alt codes specifically require numpad keys, so a normal number string doesn't work.

#Configurator code:
U"X" : '0133';

I tested it with sequences that contained non-sequentially-repeated characters and it ran just fine.

U"A" : U"A", U"B", U"A"; output "aba" as expected.
