[BUG] - Error with circle display when filtering only one location

[valentinvdb]

Describe the bug When showing several locations with the circle display and a data field for the size of the circles everything works as expected. If I filter only one item (location) using a slicer, then I get an error "layers.circle.paint.circle-radius[5]: Input/output pairs for "interpolate" expressions must be arranged with input values in strictly ascending order."

To Reproduce Steps to reproduce the behavior:

• with a table containing several locations with longitude, latitude, name or ID, and a value each for the circle size (e.g. integer)
• map the locations in the visual, with longitude, latitude, and the size field set to the one containing the integers
• add a slicer for filtering e.g. on the name or ID for each item in the table
• everything should show-up correctly as long as there are at least two locations to display
• filter only one item in the slicer
• the error sentence shows up instead of the map

Expected behavior The map should zoom in on the location, and show one circle.
