Investigation: differences between charts behaviour for DEA data services

For DEA Waterbodies, the user can click on multiple waterbodies and then click "Expand" on the Feature Info popup to get a unique chart for each (e.g orange and blue in the left image). However, doing the same thing for DEA Coastlines only ever adds a single orange chart which replaces the previous chart (e.g. orange in the right image). I am almost certain that this used to work on version 7 of Terria, but I can't work out why it still works for DEA Waterbodies but not Coastlines. I've created a minimal example below: the two charts are set up slightly differently due to different input data formats, but both add a unique ID and title to the chart (a UUID for Waterbodies, a coordinate string for Coastlines):

Waterbodies:
