luci-theme-bootstrap: Invisible checkbox borders in Pale Moon browser

Is there an existing issue for this?

Actual behaviour

All check-boxes in the LuCi interface are invisible when the panel is viewed in Pale Moon browser. The browser developers were already contated about this issue, but the response was that the browser actually properly handles the CSS code, it's just that the checkbox border is set to be invisible in the CSS code and it does indeed seem to be the case when we look at the code.

I determined which css causes this:

input[type="checkbox"],input[type="radio"] {
	--bd-color:var(--border-color-high);
	--fg-color:var(--text-color-high);
	appearance:none;
	-webkit-appearance:none;
	width:14px;
	height:14px;
	color:var(--fg-color);
	position:relative;
	display:inline-block;
	cursor:pointer;
	background:none;
	border:none
}

And removing:

border:none

Fixes this issue, so yeah it does what it says and indeed makes the background and borders "none".

Expected behaviour

Please remove

border:none

from the CSS so that the checkbox border is visible.

Steps to reproduce

Steps to reproduce

1. Open Pale Moon browser and login to an OpenWrt router settings (LuCi) panel
