Error for valid class field assignment during rendering

[EthanStandel]

In the actual runtime case, the first two lines aren't necessary and the syntax works as expected without them. However, VSCode sees that as an error claiming that pretty and actual were never defined when they're used during awaken.

Hmm, this is because we run the typescript server with "suppressExcessPropertyErrors" set to false. Setting it to true will potentially hide actual important errors / typos so I just need to think about striking a decent balance. Maybe we could turn it on for tags only or something :)

@somebee interesting because if I define self and actual not in the return statement itself, then the properties resolve correctly. The problem with that is that every render then recreates both of those elements (which means my textarea gets rerendered every time the input is modified due to the binding updates).
