Description
Hi,
In the touch zoom example, if you touch outside of <div class="u-over"></div> and try to pinch two fingers, the zoom will immediately go to maximum.
I shot a video:
P.S.
And the second question, how can we prevent excessive zoom, in which the display does not show dots and lines?

Research direction
Start with the touch zoom example at https://leeoniya.github.io/uPlot/demos/zoom-touch.html and reproduce a two-finger pinch beginning outside the
element. Trace the touch zoom plugin's handling of that gesture and define done as preventing the immediate jump to maximum zoom, while also clarifying how excessive zoom should be constrained.Written by the indexing model from the issue text.
