Anti-pattern

Scroll inside scroll

A fullscreen widget mid-page creates a 100vh inner scroll context, trapping the user between outer and inner scrolling. Use inline (dynamic height) for mid-page embeds.

About this space

Above and below the widget is normal editorial content. The fullscreen-mode widget in the middle creates a nested scroll trap — watch what happens.

And here is more content after the widget. Reaching it requires scrolling past or out of the nested 100vh widget — friction the inline embed avoids entirely.
