pattern match with escaped-double quote being reported as error

[raven42]

I'm seeing an issue when using this along with the vscode extension where an error is reported in a regular expression string in the pattern statement when a double quote is used and escaped as per the yang RFC standards. The only way I can seem to fix this is adding two double-quotes instead of an escaped double-quote.

Example error:

Two double-quotes seems to fix this:

My understanding is a double-quote should be escaped, not two double-quotes to have it recognized.

Same issue here, also have some escaped double quotes in our codebase.
