Dragging: Horizontal movement not recognized

[ghost]

A tree does not accept a node that is dragged with almost only horizontal movement. Only vertical movement seems to be recognized. See the following example:

Tested with Chromium for Windows and Mac.

Finding the piece of code that causes this behavior isn't that hard. It's the dragMove-Method of the uiTreeNode. There's a condition if (!pos.dirAx) around line 315 that prevents the tree from accepting the node. But I haven't found a non hacky way of changing this yet.
This somehow works for me but I think it could break other setups: https://github.com/SvenJunga/angular-ui-tree-touch/commit/e12932b091f6650cb86ec7d9e89d5f3f2b1c1618#diff-2bd42e539aeba5277f65f2599dfc0338

for reference, here the code that @svenjunga metioned above in context

if (!pos.dirAx))

uiTreeNode.js#L377

@zachlysobey have you found a better solution to this than my proposed hack? This seems to be a annoying bug to many people.

[zachlysobey]

@svenjunga nope, haven't even tried or looked into it; Just tracked down that line of code in the hopes that it might make it a little easier for someone to dig into this and perhaps submit a PR.

I think I have a fix for this I will implement soon, horizontal movement is not recognized because it is checking to see if you are moving a node within its own tree to "un-nest" it. I will add a bit that stops checking for that as soon as you leave the origin tree, so horizontal movement beyond that will be recognized as a node traveling. Not sure if this makes sense but I'll have the fix soon and can show via demo rather than just explaining it.

[jacobscarter]

The fix I implemented here now uses tree IDs to determine if you are re-adjusting nestings rather than pixel measurements on the screen.
