Thanks for this PR @Albi34. Can you briefly elaborate the description your fix? Thanks!

[jeremy-albuixech]

Hi @Voles , I just added back the line that calculated the width of the placeholder element. It's on the uiTreeNode.js directive, line 135.
I believe it might have been removed in a past merge (that one if I'm not mistaken: 432c73b#diff-2bd42e539aeba5277f65f2599dfc0338).

[Voles]

Great. Is it possible to separate your other changes from this PR to keep things organised? Thanks!

[jeremy-albuixech]

@Voles I just synced my fork and updated the pull request with a cleaned-up version. Sorry about the delay, had a crazy week!

[Voles]

@Albi34 still not able to merge. I've updated the Bower.json file. Maybe it's best to only update the files in the source/ directory? So without creating the dist files.

Sorry for the trouble, I can't resolve the merge conflict myself as I don't have write access to your repository.

@Albi34 I've added you're fix to a separate branch so we can release your fix in the next version. Thanks very much for your help!
