Three changes needed to make scrollIntoView and "Locate in Gallery" work
reliably.
1. Use setTimeout to work around race condition with scrollIntoView in
gallery.
It was possible to call scrollIntoView before react-virtuoso was ready.
I think react-virtuoso was initialized but hadn't rendered/measured its
items yet, so when we scroll to e.g. index 742, the items have a zero
height, so it doesn't actually scroll down. Then the items render.
Setting a timeout here defers the scroll until after the next event loop
cycle, by which time we expect react-virutoso to be ready.
2. Ensure the scollIntoView effect in gallery triggers any time the
selection is touched by making its dependency the array of selected
images, not just the last selected image name.
The "locate in gallery" functionality works by selecting an image.
There's a reactive effect in the gallery that runs when the last
selected image changes and scrolls it into view.
But if you already have an image selected, selecting it again will not
change the image name bc it is a string primitive. The useEffect ignores
the selection.
So, if you clicked "locate in gallery" on an image that was already
selected, it wouldn't be scrolled into view - even if you had already
scrolled away from it.
To work around this, the effect now uses the whole selection array as
its dependency. Whenever the selection changes, we get a new array,
which triggers the effect.
3. Gallery slice had some checks to avoid creating a new array of
selected image names in state when the selected images didn't change.
For example, if image "abc" was selected, and we selected "abc" again,
instead of creating a new array with the same "abc" image, we bailed
early. IIRC this optimization addressed a rerender issue long ago.
This optimization needs to be removed in order for fix#2 above to work.
We now _want_ a new array whenever selection is set - even if it didn't
actually change.
This feature added a lot of unexpected complexity in graph building /
metadata recall and is unintuitive user experience. 99% of the time, the
style prompt should be exactly the main prompt.
You can still use style prompts in workflows, but in an effort to reduce
complexity in the linear UI, we are removing this rarely-used feature.
Prevents a large spike in VRAM when preparing to denoise w/ multiple ref
images.
There doesn't appear to be any different in image quality / ref
adherence when concatenating in latent space vs image space, though
images _are_ different.
