Those black tooltips pop up everywhere on the side or bottom and especially on mobile devices quite often they're stuck covering up buttons until I actually re-open NodeRed. This is particularly annoying since screen realestate is so limited here and they are actually not relevant as they mostly refer to keyboard shortcuts. Changing what I perceive as the relevant settings doesn't have any effect. I am using the iPad and occasionally also the iPhone, as I often tweak and test while I am away from the office. I use v4.1.1 and also v5.0.7 where it’s much worse as there are more of them.
I suspect there will be something around the touch events on these devices we aren't handling in the same way as mouse events on desktop environments. If you can, please do raise an issue on github so it doesn't get forgotten.
I have seen it using Brave on Ubuntu but not managed to identify how to replicate on demand. Specifically I have seen it on the Lock tooltip in the explorer pane.
OK, I can trigger it by moving the mouse up and down over the Hide, Enable and Lock button area. Interestingly the tooltip that appears may be outside the area of mouse movement.
