vscode-terraform: `tags = {` breaks syntax highlighting

Not sure if this belongs here or at hashicorp/terraform-ls, but the following block appears to break any subsequent stanzas:

resource "aws_instance" "test" {
  tags = {
    A = "thisisfine"
    B = "this is not fine"
    C = "neither.is.this"
  }
}

resource "aws_instance" "test2" {
    tags = {}
}

Expected result:

Proper syntax highlighting with "this is not fine" and "niether.is.this" being highlighted as strings and the next block being highlighted normally.

Actual Result:

Removing only B = or C = lines still gives a broken block, each of those lines appears to break the parser. Removing both lines and never having anything but [a-z0-9] in the tag value appears to be the only “fix”.
