Find function: omits some found strings

Description

The Find-function in the provided example seems to find all strings (all are highlighted with rose color), but on click on "Find"-button some occurences are not selected but skipped.

• Affects also the "F3"-FindNext-hotkey.
• Affects also the Find&Replace-function.

Raising priority to medium as the affected "Find&Replace" could lead to real problems at renaming nets.

Steps to reproduce

1. open attached project, open schematic: Use_Netclass_Trackwidth_Bug.zip (kindly provided by @straubm))
2. "CTRL+F" to search for "SOLDERTIP"
3. 6 occurences are highlighted at root-page, but only first occurence is selected at click on "FIND"-button, after that the "Find"-dialog jumps to page "Analog"
4. on page "Analog" all 4 occurences are found (highlighted) and also subsequently selected.
