Can not change properties of multiple artboards
Consider a file that has 100 artboards. All of them need to be exported as PNG files with transparrent BG, when selecting ALL artboards, or any number of artboards above 1 and then clicking into PROPERTIES the panel says "no properties". This is not true. All of those artboards have the same properties, a white BG that needs to be set to TRANSPARRENT.
TO REPRODUCE:
Create any number of artboards and try to select them all and change their BG to transparrent or change any of their properties from the properties panel. The properties panel says "no properties" - this is not true
EXPECTED BEHAVIOR:
When selecting multiple artboards to change their properties the properties panel should allow them ALL to be changed when ALL are selected.
PROBLEM:
