QmlProfiler: Searching for notes does not work

Steps to reproduce:

• profile a quick application to have some profiling data
• add some notes
• try to search for them

Current result:

• sometimes I can find notes, sometimes not - it's unclear why (or why not)

Example I've used [square brackets contain my 'notes']:
(1) inside SceneGraph: 3 blocks located next to each other (GUI Thread)
[bla, sdfsdfsdfsdf, sdfsdfsdfsdfsdfsdf]
(2) inside Compiling: 1 block [blobb]

Search for 'b' or 'o' or 'bl': presents me sdfsdfsdfsdf or blobb
Search for 'blo': presents blobb
Search for 'bla': presents sdfsdfsdfsdf
Search for 'df': presents me sdfsdfsdfsdf

Feels like I'm never getting 'bla'
