When double-clicking inside quoted string, between 1st and 2nd characters, almost complete string is selected, except first and last characters. E.g. when double-clicking inside "abcdef" between "a" and "b", a part "bcde" is selected, "a" and "f" remain unselected. This happens only when selecting Alabaster Theme from the theme list.
It's not clear how the theme that defines only colors in json does that, but the issue doesn't occur when using other theme extensions (like GitHub Theme), although some (Dracula Theme Official) lead to deselecting everything.
