Title edit function shuffling lines

[treespan]

Describe the bug: Editing a multi line title from a template created in Inkscape, lines that have previously been blank are not listed for editing, and after saving the edit the lines become reordered.

Steps to reproduce the behavior:

1. Open a new project
2. Add a multi line title
3. Drag this title into a track
4. Right click a title in the project titles box and select "Edit title"
5. Delete the first line to leave it empty
6. Save the title
7. Right click a title in the project titles box and select "Edit title" again
8. The text entry box for the first line is now absent, so it starts with line 2
9. Edit the text on the final line replacing what was already there
10. Save the title
11. Examine the current state of the title: the last line remains how it was before the edit and the new text has overwritten the last but one line (the edit has shuffled up one line)

Expected behavior: The edited text should remain in the line it was put, and the first (empty) line should still be listed to enter text into

Hello @treespan . Thank you for reporting this. Essentially, two issues exist:

1. The fact that you lose one of the lines.
2. The shuffling of the text.

I am able to reproduce both of these issues running the latest dev daily build #11909 as of this writing in Windows 11 Pro environment. So at least it is consistent across different platforms.

Issue #1 has been reported previously here: https://github.com/OpenShot/openshot-qt/issues/5409. It is has been captured and in the queue to be fixed (no ETA).

Issue #2 (shuffling) is new so I am going to add it to the same issue in step one.

The line disappearing is not a bug but rather a choice the development team had made. However, I agree that it should remain even when blanked out so you are able to "Edit Title" and add text if you choose to do so.

The "shuffling" is definitely a bug and needs to be fixed.

Here is the link to the Trello card capturing these issues: Multi-Line Text - Blank line and shuffling. Sometimes the link doesn't get you there but you can used the "Filters" feature to search for card #168
