Research direction
Start by tracing Plotly.Fx.hover and the internal callback that moves hovertext with the cursor. Review the related issues #7578 and #998 alongside the linked D3.js prototype. Done should mean a click freezes the current hovertext location, a second click restores cursor movement, and programmatic hover remains usable.

Description
Description
I would like to freeze the location of my hovertext with a click callback. Once frozen, the hovertext would no longer follow the cursor, but instead be frozen in place. Another click would release the hovertext, so that it follows the cursor again. I feel like this should be possible by temporarily disabling the internal plotly callback that moves the hovertext with the cursor.
Why should this feature be added?
There are two ways for moving the hovertext. You can move it with the cursor or you can move it programmatically with Plotly.Fx.hover. If you are moving the hovertext programmatically, it is helpful to 'turn off' the cursor interaction, otherwise the user may inadvertently move the hovertext when they move the cursor. In my project, the user is trying to find an 'optimal' location in the heatmap. I think it would be useful if they could make an initial placement of hovertext using the cursor, click to freeze it there, and then make subsequent 'tweeks' to the hovertext location using input fields elsewhere in the app.
Mocks/Designs
This prototype is built from the D3.js heatmap example and a global frozen variable as suggested on StackOverflow. Notice how the tooltip follows the cursor until the user clicks, whereupon the tooltip is frozen at the clicked location until the user clicks again and unfreezes the tooltip. I would be happy to neaten & share the code if that would be helpful.
Notes
- Similar to #7578 but slightly simpler, since I am not seeking to make comparisons between different parts of the same plot.
- Similar to #998 in the sense that I want to persist the hovertext on click.
- There is a workaround for temporarily disabling all mouse interactions on StackOverflow.
