Description

It looks like the rename happens based on the last known location for a token. This means that if you create a syntax error in your script and try to rename something, the location of the tokens may be outdated and the new name is inserted in the wrong position.

Video is attached that shows this happening. The syntax error in this case is an unbalanced piece of JSX.

Research direction

Reproduce the issue in the VSCode plugin by introducing an unbalanced JSX fragment, causing a build failure, and then invoking rename as shown in the attached video. Trace the rename handling from that scenario and verify that the new name is inserted at the token's current location rather than its outdated location.
