	has-text-text.is-hoverable:hover,
	has-text-text.is-hoverable:focus-visible {
	color: hsl(var(--bulma-text-h), var(--bulma-text-s), calc(var(--bulma-text-l) + var(--bulma-hover-color-l-delta))) !important;
	}

All in all, there are styles for :active, :focus-visible, :hover for each of the following elements.

• <has-background-black class="is-hoverable" />
• <has-background-danger class="is-hoverable" />
• <has-background-dark class="is-hoverable" />
• <has-background-info class="is-hoverable" />
• <has-background-light class="is-hoverable" />
• <has-background-link class="is-hoverable" />
• <has-background-primary class="is-hoverable" />
• <has-background-success class="is-hoverable" />
• <has-background-text class="is-hoverable" />
• <has-background-warning class="is-hoverable" />
• <has-background-white class="is-hoverable" />
• <has-text-black class="is-hoverable" />
• <has-text-danger class="is-hoverable" />
• <has-text-dark class="is-hoverable" />
• <has-text-info class="is-hoverable" />
• <has-text-light class="is-hoverable" />
• <has-text-link class="is-hoverable" />
• <has-text-primary class="is-hoverable" />
• <has-text-success class="is-hoverable" />
• <has-text-text class="is-hoverable" />
• <has-text-warning class="is-hoverable" />
• <has-text-white class="is-hoverable" />

Here's where they are generated:

1. Are these elements used somewhere? I think that some browsers might not allow them to be active or focused.
2. Or are they obsolete?
3. Or were they supposed to have been class names? In that case, can they be removed since they haven't been missed?

While the documentation refers to most of these as classes, this doesn't seem to be the case with has-background-text and has-text-text.
