allow larger zoom when previewing picture(s) to upoad

[mnalis]

What is the user problem or growth opportunity you want to see solved?

• Zoom is too weak (maybe 30% or so) when zooming in already selected picture (by minimizing Step 1 of 4: Media Details via triangle). It is almost as there is no zoom at all! Normal app gallery (or third party ones like Fossify Gallery allow high zooms, like 500%, which allows one to see even tiniest details.

• Same problem with too weak zoom is present in custom picker zoom, see Custom picker: Allow deeper zoom #5701

How do you know that this problem exists today? Why is this important?

well, it is present in Commons app 5.0.2. It is especially important for commons app, to differentiate pictures (if uploading multiple of them), to read / retype inscriptions in picture metadata etc. It is all impossible with "too weak" zoom

Who will benefit from it?

Every contributor who wants to see details in pictures

Anything else you would like to add?

Here is example video of how little the zoom is (first zoom is strong, in Fossify Gallery, and the second in Commons app is very weak):
