Investigate quick suggestions inside quotes

[paultyng]

See this issue in VS Code: microsoft/vscode#23962 (comment)

Identifiers (block labels, etc) are commonly inside quotes, we should enable completion inside them if possible.

For the time being, this seems not to be actionable because (per the linked comment) we cannot change the editor setting for users that disables automatic suggestions. I'm going to make this as needs-research to figure out whether other extensions have figured out workarounds.

A future possible solution within LSP is being discussed as part of these threads:

• client/executeCommand microsoft/language-server-protocol#1119
• Specification to open a second completion after apply a completion item microsoft/language-server-protocol#565
