### Description

Trying to produce a GIF from a source with transparency leads to a broken output.
Since I cannot attach the WEBP, I uploaded it [here](https://files.catbox.moe/kh218j.webp)
The broken output is attached below.
If needed, I can provide more WEBP files, just ask.


### Steps to Reproduce

1. Pick a WEBP file or similar with alpha/transparency which you want to convert
2. Run `convert input.webp output.gif`
3. Observer the broken output
