graph 'draggable:true' with legend problem

Version

5.5.1

Example

Steps to Reproduce

drag some nodes and select a category from legend

Current Behavior

After dragging some nodes and selecting a category from legend, all nodes are reset to their original positions, i.e. the manual repositioning is lost.
I wouldn't call it a bug, but it isn't right behavior either. Why bother to rearrange a graph when a simple legend click will reset it?

Expected Behavior

Legend is about node visibility only and should not affect node positions.

Environment

- OS: win 10
- Browser: Chrome
- Framework: none

Any additional comments?

The documentation for draggable says:
"Note that this option is only available when using force-directed layout before v5.4.1."
But draggable works for layout:'none' too and makes sense only in this context.
