@Mlocik97-issues This bug tracks the specific case:

`${|`

Case such as:

`${|}`
`${| `
`${| x`

were fixed by #34857

Basic issue is that we can't distinguish:

`${`

From valid code like:

`${`abc`}`

In that case, quick suggestions should not be shown since you would be inside of a string again

@mjbvz seems the same as 1.21. I can trigger manually but it doesn't autotrigger when I type c.

Broke when I changed to using selector matching instead of direct comparisons for scopes. Will require a fix on vscode textmate
