Test file

Steps to reproduce:

- Open the attached test file: `at-nested.html`
- Inspect the `body` element
- Click to edit the inline style `display: block`
- Press Tab repeatedly to navigate forwards to the next rule's groupings, selector and properties.

Expected:

I should be able to tab into @media, @supports, then selector of the next rule

Actual:

The @media and @supports editable condition text fields are skipped when tabbing to navigate forward.
Navigating backwards with Shift + Tab will correctly focus the editable fields.
