Cannot save "bookmark" and "caret positions" for multiple files at the same time

[4512369781]

Version: Notepad3_6.24.309.1_rc3_x64

Steps to trigger the problem:

1. Clean install and enable "Preserve Caret Position".
2. Prepare two text files named "file1" and "file2" and open them.
3. Set bookmark on file2, change the caret position, and then close file2.
4. Open file2, check the bookmark and caret position, everything is ok at this time, close file2.
5. Close file1.
6. Open file2 again, the bookmark and cursor position have been reset.

I found that some settings, such as changing "global default font" in step 2, were also reset after closing file1.
But changing the language is no problem.
