Text color issue

When adding typography text color to parent element, child elements have it even if it is reset on the parent.

Namely, add to parent element color "#666", save in the editor. Remove color, and it stays to child elements, those are not reversed to default as it was before.

With some digging it seems like it is applied for anchor tags inside parent:

.blockera-block.blockera-block-oi0egg a:not(.wp-element-button) {
color: #666 !important;
}
