It happens from time to time, and I don't know if this is my mouse, or a webflow bug,
but it happens that sometimes I accidentally and unwillingly grab an element on the page,
which makes it directly disappear from my view, and I don't understand where it goes,
because to me I was not grabbing it.
And I realise that it is being hold within the Navigator pannel and I can't do anything to release it,
even ctrl+Z do not work in this situation.
I do not have a clear answer to that, but I do know that a similar behaviour also happens on Illustrator.
It would be nice to have an option to «stop all action» and back to previous step, or action.
