Hi Team,

While going through WPT test cases, I came across following failing two subset test cases:

WPT Link: https://wpt.fyi/results/html/dom/render-blocking/remove-element-unblocks-rendering.optional.html?label=master&label=experimental&aligned&q=option%20element

WPT Live Link: http://wpt.live/html/dom/render-blocking/remove-element-unblocks-rendering.optional.html

From above, Safari is only browser failing two sub-tests for 'defer' and 'module' script.

I thought to raise this, so we can track it for future.

Thanks!
