Fixes #567.
Matplotlib PR matplotlib/matplotlib#28453 added the use of
event.buttons
in mouse event messages that are handled by backends. We need to support the same here, otherwiseipympl
does not work interactively withmatplotlib >= 3.10
.It is a simple one-line fix, the same as at
https://github.com/matplotlib/matplotlib/blob/0400863b7a0d660d9333242fabd83dbfe3496503/lib/matplotlib/backends/web_backend/js/mpl.js#L647
It works for both matplotlib 3.10 and <3.10, as with the latter the new argument is just ignored.
