I've tested the changes on Android using a Pixel device in two ways:

• On an Actual Mobile Device: I accessed the application through the browser on my Pixel phone and confirmed that the equations rendered correctly.

• Via Browser Simulation: I also used the 'Toggle Device Toolbar' feature in Chrome DevTools to simulate a Pixel device and verified the behavior.

Both tests showed the issue is resolved, and the equations render as expected with the invisible elements in place of the empty tags.

Since I’m new to open source contribution, I’d appreciate your input on whether this is the correct approach for testing Android behavior.

In this particular case the reason the images are there are for input reasons rather than rendering reasons. I think your testing approach is correct, but it sounds like you were testing the wrong thing (rendering instead of input). Probably the best thing to do here would be to set CSS and/or an src on the img tags so that they don't show placeholders on Safari, which is less likely to cause an input regression on Android.
