Scroll position not restored correctly when switching documents after font size change

[RaymondLim]

1. Start Brackets with default font size. If you have changed font size before, then you can press Ctrl+0 to restore default one and reload with Ctrl+R.
2. Open a document with at least 300 lines and scroll down to the bottom of the page. Remember the line number of the first visible line.
3. Open another document and then press Ctrl++ to increase font size.
4. Select the document opened in step 2 in the working set.

Result: The document opened in step 2 is now using a larger font, but the first visible line is not the line you remembered in step 2.
Expected: Should adjust scroll position to maintain the anchor line of the visible area.
