PointDraw tool not immediately responsive in PolyAndPointAnnotator

[kcpevey]

Recipe:

1. Annotators.ipynb - Run All
2. go directly to the PolyAndPointAnnotator
3. Click PointDraw
4. Try to click and drag a point - it will not work

After some clicking around, selecting other tools, etc, the PointDraw tools does eventually start working.

I can reproduce, deactivating and reactivating the draw tool seems to fix it.

Can't immediately see an issue in the code, and the odd thing is that adding a point does work.

@philippjfr This should probably be resolved before exporting the annotators

Totally independent issue that's pretty deep in bokeh itself, but yes high time this is addressed.

@philippjfr I think this was fixed. Was it?
