Transparency slider disappears when using image registration (Chrome/Edge only) #145
Description
Description:
When opening in a registered image pair and navigating within the image (panning), the transparency slider above the image becomes inaccessible. It either disappears entirely or shifts underneath the navigation bar. This prevents adjusting transparency of the 2 registered images.
The issue occurs in Chrome and Edge, but not in Firefox.
Steps to reproduce:
- Open an image that has a registered image pair.
- Navigate within the image (pan).
- Observe the transparency slider above the image in Chrome/Edge.
Expected behavior:
The transparency slider should remain visible and accessible during registration and while navigating, regardless of the browser.
Observed behavior:
In Chrome and Edge, the transparency slider intermittently disappears or moves beneath the navigation bar during navigation when registration is active.
In Firefox, the slider remains visible as expected.
