Scattergl reports 'Cannot read property 't' of undefined' when hovering over data

I’m using a scattergl plot with gaps in data points.When I hover over the gaps, errors are reported to the console. Is there some way to get around this? Scatter seems to work but I’d really like to use scattergl.

Hmm. Using your https://codepen.io/TMS8503/pen/YzKvBdY codepen, hover seems to be behaving fine and I didn’t notice any console errors.

Where exactly “over the gaps” are you hovering on?
