I\'m trying to use the auto-indentation feature in Sublime Text 3 for HTML. I\'ve got some block comments in the html and selecting Edit>Line>Reindent works until it hits a bloc
Tried your example in Sublime Text 3 (builds 3103 and 3114) and you are right, the indentation breaks when it finds a comment block.
Apparently, the reindentation functionality was always pretty weak and HTML is not the only context where it doesn't work (EDIT: Confirmed in PHP too, pretty much the same behavior).
I'd recommend submitting the issue if it isn't already submitted.
