I got a minimal reproduction code like the following:

variable "foo" {
  default = "foo"
}

foo = "%{if true}${var.foo}%{endif}"

And I created the PR to HCL repository https://github.com/hashicorp/hcl2/pull/125 Maybe it fixes the issue.

(Reopening because the change in the HCL repository can't fix this until it's vendored into this repository.)
