Code change:
Issue Type: <bBug</bWhen working with tagged template literals in JS and JSX (styled-components is my use case), the backticks used to auto-close when typed, but that recently changed. The big issue though is that if you go into a multi-line literal, and then try to type the closing backtick, vscode inserts two backticks, leaving you with three. For example if I type: I would expect to have the closing tick automatically inserted and the cursor in between them. Instead it just stops there. If I then go on to enter some css and then manually enter the closing backtick, I get: I then have to manually delete the third backtick, as if I delete the second, the whole pair is deleted because of the auto-close rules. I have verified this is happening on Mac and Windows 10, with extensions enabled and disabled, and in the Insiders build.

It seems to me the editor only adds backtick if it's legal for a template string to be in that place. However your example is only legal if styled components are allowed. Could you give an example with a valid js syntax? If it only happens with styled component syntax, could be it's a bug (or a lack of feature) in the styled component extension.
It works with just plain ES6 syntax as well. This example: Is valid ES6, no React/styled-components, and the same issue occurs when trying to type the multi-line literal. I should note that manually closing the literal on the same line does work okay, although it doesn't auto-close. It is only on multi-line template literals that the auto-close fires on the last tick.
I'm seeing this bug also in python, where backticks have no special meaning . Sometimes I use them to denote arguments in a user string: But when I type the second backtick, vscode inserts two, resulting in: Strangely, this only happens if there is before inserting the backtick. If I type insert in any other part of the string, the doubling doesn't happen. should I open a different issue with this problem, to be tagged as a bug? If so, does it belong here or to ? Thanks !
Can this be for this iteration?
As a workaround, set: Opened to track possible solution
Thanks for that! Anything workaroundish for the cursor coming inside to the next line with an indent on press Enter? !
FWIW, I found disabling the Babel JavaScript extension put a stop to doubling up on backticks when closing a pair. (However as I rely on that extension, disabling it isn't really an option.)
