I believe we have other bugs for too-big padding on form controls on ubuntu.

I don't understand how this can be a regression.  It's quite clearly
a mistake in the styling on the site:

.dg .c select {
	margin-top: 5px;
}

.dg li:not(.folder) {
	cursor: auto;
	height: 27px;
	line-height: 27px;
	overflow: hidden;
	padding: 0 4px 0 5px;
}

Any form control that doesn't fit within 27px will be clipped.
The <select> seems to render as expected for me, but it's clipped
because it's larger.  That's not a bug in Gecko, it's a bug on
the web site.

Mike, should we file an issue on their repo?

Thanks, yeah.

The example is at https://github.com/mrdoob/three.js/blob/dev/examples/webgl_animation_skinning_morph.html

https://threejs.org/examples/js/libs/dat.gui.min.js is what powers the control thingy.

Let's file an issue: https://github.com/dataarts/dat.gui
