Why is zoom so insane when you double tap on images?

When you click on an image and double tap to zoom, it zooms to the microscopic level or is it just me?

as an alternative to pinching, you can tap, hold, and drag in that order to control the zoom level with one finger.

  I think everyone that knows it discovered it by accident when panning

- That's an uncommon way of controlling zoom. I think it probably should be changed to something people are used to

  Double tapping and holding on the second tap for granular zoom with one finger is a standard feature on Android.
  
  The person you're replying to is just suggesting an alternative for one-finger zoom. Pinching with two fingers still works.

  Isn't pinch to zoom the norm? I've never double-tapped an image to zoom.

  I know at least Firefox and Signal do the same. I don't see why it should be changed, since pinching and double tapping are also supported. Although, the zoom on double tap is indeed way too strong.

This is because of the library we use for Jerboa. Too allow zooming in a lot, I have set the maximum zoom factor to a high number. The behaviour of double tap is to zoom to maximum zoom factor. So as consequence it now instantly zooms in a lot when doing double tap zoom.

I have filed a feature request to change this behaviour. https://github.com/saket/telephoto/issues/88
