Slider: Revision page slider does not support touch interactions on mobile devices

[yogeshbhutkar]

The slider on the revisions page lacks touch interaction support on mobile devices, making it difficult for users to navigate revisions using touch gestures. This limitation affects the feature's usability and accessibility on touchscreen devices.

To replicate, perform the following steps:

1. Create a post and ensure it has at least five revisions.
2. Open the revisions page.
3. On a mobile device, attempt to drag the slider.
4. Verify that the slider does not respond to touch gestures.
