@bind doesn't update values within the same cell

[aplavin]

A cell containing both @bind and a reference to the binded value does not keep them in sync.
E.g. create this cell:

md"""
$(@bind x Slider(0:10))
x = $x
"""

and drag the slider around. It always shows "x = 0" on the second line.

Hi @aplavin!
That's on purpose, if the cell would run again with your new value, then it would also create a new slider, which is set to its default value. So you wouldn't be able to move the slider.
