[Resolved] element for Skip to content produces HTML validation error

Here is the full text of the style element that is causing the problem:

<style id="skip-link-styles">
		.skip-link.screen-reader-text {
			border: 0;
			clip: rect(1px,1px,1px,1px);
			clip-path: inset(50%);
			height: 1px;
			margin: -1px;
			overflow: hidden;
			padding: 0;
			position: absolute !important;
			width: 1px;
			word-wrap: normal !important;
		}

		.skip-link.screen-reader-text:focus {
			background-color: #eee;
			clip: auto !important;
			clip-path: none;
			color: #444;
			display: block;
			font-size: 1em;
			height: auto;
			left: 5px;
			line-height: normal;
			padding: 15px 23px 14px;
			text-decoration: none;
			top: 5px;
			width: auto;
			z-index: 100000;
		}
</style>

I found this exchange in the support forum that pointed me in the direction of GeneratePress’s screen reader functionality:
https://generatepress.com/forums/topic/screen-reader-text/

It turns out my posts contain the following link that gets styled by the problematic style element:
<a class="screen-reader-text skip-link" href="#content" title="Skip to content">Skip to content</a>

While removing the generate_do_skip_to_content_link action per the above forum thread does indeed remove this screen reader link, the style element remains.

Are there third party plugins that style the GP “skip to content” link?

Thank you, I disabled Gutenberg and it went away.
