Remove `optgroup` element

[cevdetta]

In modern-normalize.css file, there is a reset for form elements:

/**
1. Change the font styles in all browsers.
2. Remove the margin in Firefox and Safari.
*/

button,
input,
optgroup,
select,
textarea {
	font-family: inherit; /* 1 */
	font-size: 100%; /* 1 */
	line-height: 1.15; /* 1 */
	margin: 0; /* 2 */
}

button, input, selectandtextareaseem fine butoptgroupis unnecessary; why you may ask, becauseoptgroupshould be a child element ofselectandoptgroupshould be a parent element ofoptionelement, we can remove it to take advantage of cascading whichselect` element does when it inherits.

The font family and font style are not inherited by optgroup labels and options within an optgroup in Firefox 45 (probably happens in some older versions too). The screenshot below demonstrates this using the normalize.css UI tests page:

Firefox 45? https://caniuse.com/usage-table
From version 2 - 45, only 0,02% of people are using it, so it's really unnecessary? In my opinion it should be deleted, we have more problems than that (which is a bug in Firefox 45, it's so small).

Firefox 45 was the latest then. It's not clear if or when it was fixed. It needs to be proven that it was fixed first.

Even before Firefox v100 the usage is only 0.11% which I might say even IE usage is 0.59% ? The thing is I don't know how to prove if it's fixed after v45 or not...
