Bug Report

Description

I am seeing the same behaviour first mentioned here with 2.46.0. Experiments appear to get stuck in the Running status after being completed.

Reproduce

1. Open the extension.
2. Run a checkpoint experiment.
3. Experiment will get stuck in running state once completed.

Expected
