float: true pushes widgets down before releasing moved/resized widget

[mlbaquerizo]

Moving/Resizing a widget should not affect surrounding widgets until that widget is released.

In the case where a widget is expanded or moved and then placed back to its original position (made smaller or placed out of the way) before releasing it, I would expect the surrounding widgets to move back to their original positions as well. This doesn't seem to be the case as affected widgets are pushed down and remain there.

this is no longer the case with current release - see https://gridstackjs.com/demo/two.html
(I thing we use ._origY for that).
