### Description f-strings with escape braces (i.e. '{{' instead of '{') are not rendered correctly. Here is a code snippet that shows this glitch: ```python a=1.1 b='g' f'{a:{b}}' # → '1.1' f'{{{a:{b}}}}' # → '{1.1}' f'{{{a}}}' # → '{1.1}' ``` Here is how it is rendered in atom:  I would expect the characters `{a:{b}}` to be rendered equally in lines 3-4 and `{a}` rendered non-green, but this does not happen. ### Versions language-python version 0.53.4 <!-- You can get this information from copy and pasting the output of `atom --version` and `apm --version` from the command line. Also, please include the OS and what version of the OS you're running. -->
