Use of a comma (,) in a Build Artifact Label causes odd results

When using a comma characters: , as apart of a Build Artifact Label; the resulting page after saving the entry shows the label in square brackets. E.g. [I like cheese artifacts]. Additionally, a spurious artifact entry is created; which, when deleted: causes all characters from the comma onwards to be deleted:

Entering the build artifact

Saving the build artifact entry with resulting oddball behaviour

After removing spurious entry

Seems that for each comma used, you get a spurious table entry:

What happens if I delete one in the middle?

Looks like it will nuke the label from the first comma onwards.

bmccoy has hypothesised that this is caused by the string being interpreted as an array, which is coroborated by the label truncation seen when deleting the spurious lines.
