Does not ignore Latex commands if command is preceded by backslash

[MeAmAnUsername]

The checker ignores Latex commands (word preceded by \), but not if the command is preceded by one or more escaped backslashes (\\)

Text from the image:

askjdh      % Correctly flagged
\askjdh     % Correctly ignored
\\askjdh    % Correctly flagged
\\\askjdh   % Incorrectly flagged
\\\\askjdh  % Correctly flagged
\\\\\askjdh % Not flagged? Seems to be a caching issue
\\\\\askjdg % incorrectly flagged
\\\\\askjdd % incorrectly flagged

For five backslashes, it does not give an error for askjdh but it does for other incorrect words. Some experimenting brings up the hypothesis that it does not give errors on the same word after a certain number of occurrences. Either way, that's not what this issue is about.

Expected behavior: ignore commands, i.e. ignore words preceded by an odd number of backslashes
Actual behavior: it ignores words only if there is exactly one backslash in front of it
