Research direction

Reproduce the two f-string examples from the issue in a supported editor, then trace the Python syntax-highlighting implementation that handles expressions containing newlines. Done means the multiline expression highlights correctly while the single-line example remains correct; add or run the relevant checks if the repository provides them.

Written by the indexing model from the issue text.

Description

In Python files, the syntax highlighting for f-strings is incorrect when the f-string’s expression contains a newline.

print(f"{1
}foo") # new line in brace, highlighting incorrect
print(f"{1}bar")
