So according to the document, element with `pw-optional` attribute should be removed if empty but somehow I'm able to make it stay till the very end output:

From the screenshots, you can see the aside element with `pw-optional` refused to leave the party. I tried to debug it:

Seem like the render engine miss out sth.

• APPEND #site-meta with <pw-region><meta name="aaa" content="xxx" /> … 613 bytes</pw-region>
• REPLACE #site-content with <pw-region pw-id='sss'><article class="bbb"> <header class="iii"> … 4358 bytes</pw-region>
• 0.0010 seconds

• REMOVED # optional region
• REMOVED # optional region
• 0.0001 seconds

Any hint for me to do deeper debug?
