When saving a text file with Ctrl + S, gedit enables "Highlight current line" on its own

[Lyubomir]

Steps to reproduce:
1. Have some text file opened in gedit
2. Disable "Highlight current line"
3. Press Ctrl + S to save changes
4. Notice the "Highlight current line" is now enabled.

Thank you for the bug report, which locale and keyboard layout do you use?

[Lyubomir (mystiquewolf)]

My Language preferences are set in this order:
1. British English (Default)
2. American English

For keyboard layouts i have English (US) and Bulgarian (traditional phonetic), but usually use the English as active.
For formats i have the bg_BG setting selected.
