Highlighting breaks for `:has()` when combined with an operator and child psuedoclass

[giraugh]

Describe the bug (including copyable syntax) The highlighting breaks for this example using the new :has selector.

&:has(> a:hover) {
  font-size: 1px;
}

This may or may not be the same issue, but appears at least related. Syntax highlighting also breaks in the particular case shown below, but is valid CSS and handled correctly by Chrome:

.ant-input:has(+.ant-input-group-addon:last-of-type) {
  border-top-right-radius: 0 !important;
  border-bottom-right-radius: 0 !important;
}
