CI Variables stripped when inserting Duo code suggestions in Web IDE

MR: No MR

Expected Behavior

As a developer , I want to insert code suggestions from Duo Chat that contain CI variables (predefined or environment vars) via the "Insert" button in the Duo Chat UI, so that I can leverage AI to build pipelines.

Actual Behavior

Using the Insert button removes all $CI_VARIABLES (or, perhaps, it is replacing their values, which resolve to empty strings). See attached screenshots of the Duo Chat response, and the inserted yaml.
