Definition of a trope by Merriam-Webster:
Full Definition of trope. 1a : a word or expression used in a figurative sense :
figure of speech b : a common or overused theme or device
The "Flaming Emblem" entry under TV Tropes for when a character has their logo recreated using fire of some sort has 6 different entries under film including: your 3 examples, Eric Draven in "The Crow", a V made of fireworks for "V for Vendetta", and the Zorro 'Z' in "The Mask of Zorro".
Using Merriam-Webster's definition, I wouldn't really call it a trope yet, but I also wouldn't call it a coincidence. I would imagine multiple directors saw the idea and wanted to create something similar.
But then again it's listed in TV Tropes so take that as you will.
