Update lora/model combo preview

[christian-byrne]

This PR resolves #413 by updating the lora/model combo preview to work with Comfy-Org/litegraph.js#414.

Changes include:

• Use constant for width/height of preview image
• Attach image preview to body instead of the context menu directly, as the context menu no longer shows overflow
• Add mouseenter, mouseleave, and click handlers to manually calculate and update the position/visibility of the preview image

Thank heavens, this took forever. I was lost without it! I mean it is the main feature to see thumbs of what you have... Thank you! But after several tries... I still don't have lora thumbnails. So I give up on this node...

If you can provide browser and terminal logs and/or reproduction steps, I can try to help you fix it.

There is also an alternative for viewing thumbs of models/loras. You can use the models sidebar tab to choose model/lora, which should also display thumbs. Then, to use a model/lora, you can click and drag the item from the sidebar onto an existing loader node or onto a blank spot on the canvas and a loader node will be created automatically.

Thankyou for offring to help. I really appreciate this. As you can see from the image I don't even have thumbs on the sidebar method you mention :-(

I' don't know where the logs are that you refer to?

Happy to help. Just to verify, you do have the images in the same folder as the models with matching names correct?

By logs, I just mean if there are any errors in the terminal window you start ComfyUI with or in the browser console (F12 to show).

Little to no errors in terminal window, but there is stuff in console. Don't know if it is related.
Images was pulled through the node, so yeah all correct in that way. Everything worked fine till recently.

Errors in log are these, but all nodes load without a problem:
