Help center button too tall in IE11

[afercia]

In IE11 the Help Center button looks taller than in other browsers:

HelpCenterButton extends YoastButton which uses a CSS hack to fix an IE11 bug with min-height and flexbox.

yoast-components/composites/Plugin/Shared/components/YoastButton.js

Lines 58 to 65 in 214ee6f

	// Only needed for IE 10+. Don't add spaces within brackets for this to work.
	@media all and (-ms-high-contrast: none), (-ms-high-contrast: active) {
	::after {
	display: inline-block;
	content: "";
	min-height: ${ `${ ieMinHeight }px` };
	}
	}

So its min-height is hardcoded to 48 pixels because this value was the design requirement. If we want to change the min-height, then also the hack for IE11 needs to be adjusted accordingly.
