1. Go to https://www3.animeflv.net/anime/ooyukiumi-no-kaina#
2. Inspect Element on the star widget in the top right.
3. (Web Inspector Element opens)
4. Select the Node `<div class="Strs RateIt" data-id="3760">`
5. Ctrl click on it and choose "Break On: Subtree Modified"
6. Reload the page
7. Click on the stars (ignore the layout issue, unrelated)
8. The Source tab is opening on the line `1 === t.nodeType && (x.cleanData(gt(t, !1)), t.innerHTML = e);`
9. Try to step in.

Expected:
Step In or go to the next step, or at least having the icon in gray

Actual:
Can't step in, step out, etc.
