How to reproduce:
# Create a 2D project;
# Go to the "File" menu and select the "Save as Scene Template" sub-menu item;
# Enter quite a long scene title and click save;
# Verify, that the Inspector tab displays created scene template data;
# Go to the "File" menu and select "New Scene"
# Verify, that the "New Scene" window opens and newly created scene with the long title is displayed;
# Observe the scrollbar, which is displayed below the "Scene Templates in Project" list.

Expected Result:  Scroolbar should be displayed through all the section from the left side to the right.

Actual Result: On the left side we get some window area without the scrollbar. Added screenshot in the "Attachments" section.
