How to set a variable in a Flow to null after the Winter 24 updates?

Previously we used to be able to set a variable to null just by leaving the equals value unpopulated. It now requires a value. Is this a bug or am I missing something here...?

Flow Assign Window

The documentation seems to say this should still be possible unless this hasn't been updated yet:

HI Teeps54,
This behavior was reported by other customers too with Winter24 release. Users were able to save the assignment with null values in Summer'23 org.  There is an ongoing investigation that I am following for updates and will keep this thread updated as I have more inputs from the Salesforce Product Team.

Thank you
