Semantic highlighting does not work for variable defined in with #1328
Description
Describe the Bug
with open("foo.txt") as f: # f has no semantic highlighting
pass
x = 1 # x is colored like a variable
This does not repro in the sandbox because the sandbox has no semantic highlighting
From @grievejia
i suspect this is the same as the other semantic token issues where we really need to do an AST walk instead of relying on locations in keys (but pls double check if someone pick this up)
