An additional cause for this kind of behaviour lies in comics past.

In the beginning, comics were like garfield, just newspaper strips in a corner. Their space was very limited and so if they wanted to tell a longer story... it had to be condensed.
Even when they got their own dedicated comic books... the stories did not immediately become longer, they remained very condensed.
It was simply the common practice at the time to describe entire scenes of a story with one singular image.

This scene of Batman being briefed about something happening at the bank would be done in a singular panel, showing Batman, the police, the bank, and the water flooding out of the bank all in the same shot.
It's not a snapshot moment in time, it's more just a drawing accomodating the story.
This entire page here, in a more modern comic would take the entire issue to conclude.
