There's a lot of unnecessary space in front of the video at https://doc.qt.io/qt-6/gettingstarted.html. This is a regression from qt 5: https://doc.qt.io/qt-5/gettingstarted.html

The space is caused by

<span class="vspan"></span>

that is added before the link to the video. Removing the <span></span> completely fixes the issue for me.

Anyhow, the Qt 5 apparently uses a different mechanism to embed videos. That is, it seems to use the html generated from qtbase/doc/global/macros-online.qdocconf, while the qt 6 site is using qtbase/doc/global/macros.qdocconf. Is that intentional?
