[severity:It's more difficult to complete my work] [regression] [worked-in:16.11.5]
When defining a Code Snippet that contains at least one editable snippet literal positioned inside a C# string literal, and the user interaction through tabbing/editing finishes with the text input caret placed inside the C# string literal, ending/confirming the snippet via Enter key is not possible. The reason seems to be that the editor will prefer splitting the C# string literal into the next line (separated with " + ") instead of finalizing the snippet editing process.

Example Snippet "" Element Content:
<! [CDATA[string s = "$myLiteral$";]] >

Invoking the snippet, typing some text and confirming with the Enter key ends up with this:
! [SnippetEnterProblem.png] (https://aka.ms/dc/image?name=B9611d77298b14f46907fdfed3e193ff0637722442634760452_SnippetEnterProblem.png&tid=9611d77298b14f46907fdfed3e193ff0637722442634760452)

Notes:

• Confirming the snippet works if a text range is selected in the editor, which is what happens by default after tabbing to a snippet literal, so you have to at least type some text to override the snippet literal's default value if one is specified, or press the arrow keys to force the text selection to be collapsed to a singular caret position inside the string literal again.
• This may also affect other languages (VB, F#), though I have not tested this.

Note: you can sort-of work around this issue by confirming the snippet completion with Ctrl+Enter or Shift+Enter. Neither behavior is ideal, but better than VS "helpfully" auto-splitting the string placeholder/label.
