hi there. I've tried to track down which recent changes to hiplot resulted in my plots getting significantly harder to read, and narrowed it down to 0.1.28 -> 0.1.29 and believe this is the PR responsible.

This perfectly readable and stacked display:

turned into

which cuts off the final column name if I make the window any more narrow and causes a weird spacing issue on the right-side.

I very much support improving the visual interface of hiplot but I believe this hurt the overall experience. Would you be open to discussing some of the changes made here and perhaps a partial revert? Or am I best served maintaining a separate fork of the project? (I am not a front-end developer but am trying very hard to use hiplot in a tool I am building).

I also noticed that on Safari, this same change resulted in "ghosting" of the headers upon scrolling (and did not fix the aforementioned problem):

(that's the "rearranging" problem in safari I mentioned, the annotation divorces from the column)

Hey @mathematicalmichael - thank you for taking time to report this. Let's move the discussion to an issue rather than a closed PR (#218)
