Experiment: Add zoom and animation toggle for image lightbox #51055
Description
What problem does this address?
This builds on the image lightbox experiment using the Interactivity API, introduced in #50373, and is related to #49972 and #50029.
Some users prefer the effect of a zoom animation for the lightbox over a fade animation. Ideally, users would be able to select the animation they prefer.
What is your proposed solution?
Add support for a zoom animation to the lightbox, as well as a toggle for the behaviors UI, allowing users to select their preference when the lightbox is enabled for a particular block.
