Incorrectly generated aria-label in social widget

Hi. I have a problem with the social widget. While verifying the site with the validator, I received strange errors indicating that certain words appear as attributes in the a tag. It turned out that after entering more than one word in the Label field in the widget, only the first word is saved as aria-label, and the rest are added as attributes. Below I am sending screenshots from the WordPress playground, on which I have installed only the Astra theme. The situation there is identical to that on my site.
