When is emergency lighting required in a commercial bathroom? Does the bathroom have to be a certain dimension before emergency lighting is required?

In the event of power supply failure, an emergency electrical system shall automatically illuminate all of the following areas:

1.Electrical equipment rooms.

2.Fire command centers.

3.Fire pump rooms.

4.Generator rooms.

5.Public restrooms with an area greater than 300 square feet (27.87 m2).

from the 2018 IBC. Note that it says public restrooms

Possibly motivated by the possibility of someone who is not already familiar with the layout being caught in the dark and unable to find the door?

The IBC commentary says:
❖ The intent of Items 1 through 4 is to have emergency lighting in areas significant for emergency responders or maintenance personnel who may be trying to locate and fix the loss of power issue for the building.

Item 5 requires an emergency light in large restrooms. Given the activity, people may need some illumination to quickly get themselves ready to be able to evacuate
