Address bugs and undesirable behavior in dynamic interactive plots, including: flickering of figures that contain datashaded overlays (and related issue of datashaded colorbar requiring using ‘rasterize’, but then not being able to ‘dynspread’), pr by Jim./Jean-Luc Bokeh toolbar bug that sometimes requires the select/unselect action, and

@jbednar: can you show us where the PR to fix this issue is? @philippjfr
