The regex for doubleBackSlash does not pick up decimals https://github.com/cmhughes/latexindent.pl/blob/78d452f8fc359d828e2c8a4cac0d2c6fc92d2967/defaultSettings.yaml#L655. See https://regex101.com/r/KkFe4h/1.

Something like \\\\(?:\h*\[\h*(?:\d+\.)?\d+\h*[a-zA-Z]+\h*\]) seems to work better. See https://regex101.com/r/Wq1fZw/1.
