ID 272090 - NodeGraph search functions incorrectly with backdrop nodes

Problem summary
Searching for a backdrop node no longer pulls focus to the located node. Instead it focuses on the node graph in its entirety. 

Customer reported version
3.3v1
Customer reported platform
windows10

Steps to reproduce


1) Open Mari Example Head

2) Create a backdrop node named 'hello world'

3) Move your node graph so your backdrop node is not the focus 

4) Hit [J] and type in 'hello world'

5) In 3.1v3 and earlier, the node graph camera will focus on the node searched for. In 3.2v1 and 3.3v1 it will show the node graph as a whole.

6) Test with a different node. The focus works correctly.

Workaround
None.

Reproduced by support
Windows 7, CentOS6 and OSX 10.12.4
Mari 3.3v1, 3.2v1

Regression​
Last working version: 3.1v3

Expected behaviour
The focus should centre on the backdrop node.

Actual behaviour
The node graph zooms out to show the entire content.
