Edge triggering behavior in breadth-first view of AGE Viewer

[Amr-Shams]

Describe the bug:

When using the breadth-first view in the AGE Viewer tool on MacOS with Firefox Developer Edition, passing the mouse over some edges triggers them even if I have not passed over all of the edges. This behavior is unexpected and makes it difficult to accurately navigate the graph.

To Reproduce:

1. Open the AGE Viewer tool and load a graph.
2. Select the breadth-first view.
3. Pass the mouse over some of the edges without passing over all of them.
4. Observe that some edges are triggered even though they were not directly passed over.

Expected behavior:

I expect that only the edges I pass the mouse over will be triggered, and that passing over some edges will not trigger them.

Screenshots:

Desktop/Browser Information:

OS: MacOS Browser: Firefox Developer Edition, version 89.0b4

Additional context:

This issue only occurs in the breadth-first view of the AGE Viewer tool on MacOS with Firefox Developer Edition. I have not observed this behavior in other views or tools, or when using a different browser or operating system.
