Plan cannot be selected in Artifact Download task if the plan was found through type-ahead instead of the initial list of plans

Summary

When working with the Artifact Download task, a plan cannot be selected from the Source plan dropdown if the plan was not selected from the initial list but instead found via type-ahead in the field. This only affects Chrome.

Environment

• Bamboo 5.10.3
• Chrome 49.0.2623.112 (Firefox is not affected)

Steps to Reproduce

1. Log into a Bamboo instance that has many plans (more than 25)
2. Edit a plan and select a job to edit
3. Click Add task
4. Click Artifact download
5. Expand the Source plan dropdown, but do not select an entry from the list ("the initial list")
6. Click in the field and start typing the name of plan that is not displayed in the initial

Expected Results

The resulting plan in the list is clickable and clicking it populates the Source plan field with it.

Actual Results

1. The plan is not clickable.
2. Clicking outside the field and subsequently clicking Save returns error Specified plan key is not a valid key and now populates the Source plan field. A subsequent Save works without errors.

Workaround

If available, use Firefox. Alternatively rather than clicking the plan, click outside the field, click Save (an error will now occur, but the Source plan field will now be populated with the plan you wanted to select) and click Save again.
