CSS tagged template literals don't self close

[ferdaber]

Before VS Code v1.27, the following would happen when creating a CSS tagged template literal (note that this issue happens with styled components, or any tagged template literal function name that triggers CSS highlighting):

const foo = css
// press the tickmark (`) key
const foo = css`|` // cursor is in the middle of two tickmarks, and the literal is self-closing

Now, this is what happens:

const foo = css
// press the tickmark (`) key
const foo = css`| // cursor is after the first tickmark, and it is not self closing
// press the tickmark (`) key to close the literal
const foo = css``|` // two tickmarks are inserted and the cursor is after the second one

I can confirm that this does not happen with any other names, for example this still works:

const foo = html
// press the tickmark (`) key
const foo = html`|` // cursor is in the middle of two tickmarks, and the literal is self-closing

I'm not sure where to file this issue, I would think that it's related to the CSS language detection part of the plugin, but I can confirm that it only happens with CSS-highlighted tagged template literals, and also only when this plugin is enabled.

Can confirm, I though it was the styled components extension, but after messing around with extensions a bit more, the problem is with vscode-language-babel. e.g. -

When you type in the templet literal quote marks, it adds 1 but doesn't seem to recognise it, and then when you try and complete it, vscode adds one more at the end, so you end up with 3

Sorry for the delay, I've been away for the past couple of weeks. I will hopefully be able to take a look this weekend.

This appears to be an issue in VSCode itself. I'll keep track of this and update accordingly.

I haven't tried this myself, but it seems that setting "editor.autoClosingQuotes": "always" is a workaround for this issue

Closing this since there is a decent workaround and vscode's fix should suffice.
