ResizeObserver loop completed with undefined notifications

During searching in Discovery section of Kibana I periodically get the next Error

What could be the reason of it and how to get rid of it?

What browser are you using?

@Marius_Dragomir,

Mozilla FIrefox 69.0.2 (64-bit)

And does it still happen if you use Chrome? Is it a specific action you do on Discover or it's just random?

@Marius_Dragomir

have not tired with Chrome yet. It happens with searching by using metricbeat indices in Discovery. With all other indices all seem to be fine.
