    <thetext>The gaze glow region for the default slider thumb size is much larger than the thumb. Originally my opinion was that the gaze glow region should match the hit region for 310265@main, but I did not realize unstyled switch thumbs would be affected; the default hit region is expanded both in WebKit and in UlKit. UlKit&apos;s gaze glow does *not* expand to match (at least at the default size).</thetext>
