Why do my line spacing settings revert from "compact" back to "loose" on macOS 10.15 in MATLAB R2020b?

I noticed in MATLAB R2020b that the MATLAB command window preferences found in "Preferences" -> "Command Window" ->"Text display" -> "Numeric display" -> "Compact" preference is not persistent. This setting periodically sporadically defaults back to "loose". There is no pattern related to when the setting reverts and it can occur within the same instance of MATLAB.

This happens if you modify the line spacing setting to be different from the MATLAB factory default setting, "loose". For instance, this issue can occur after changing the setting to "compact" and then making use of features that do not involve display at the command line or format (e.g., Live Editor).

As a workaround, create a user-defined startup script and add the following command to it:

format compact

For more information on creating a user-defined startup script, you can access the release-specific documentation by executing the following command in the MATLAB R2020b command window:
