I tried displaying images on wezterm. Using the imgcat command, I was able to display jpg and png files, but webp still images cannot be displayed (to be specific, the area where the image should be displayed is filled with black pixels).

Despite this, webp animated images can be displayed! Is this a specification of imgcat, or is it a bug on the wezterm side?(By the way, this phenomenon was also reproduced on Linux (Rocky Linux 9).)
