Updated INI Values not Used When CopyQ Starts - Suspect Memory Corruption

**Describe the bug**
I'm using "**notification_bg**" value as my "canary". If the INI works non-native notifications should display on black on yellow. When the INI fails it is white on black.

This didn't happen in the previous release I was using (v4.3 I think on Windows 10) but happens in 6.1.0 (at least for the same data/ini file).

**Files for Test Case/Reproduction**

**To Reproduce**
Steps to reproduce the behavior (on COPYQ 6.1.0):
1. Stop CopyQ 6..1.0
2. COPY the INI I have attached (1.MoreComplex-Fails-[get white on black]-copyq-DBAREIS-TOOLS-commands.zip)
3. Start CopyQ
4. Do something that causes a notification (invalid command etc)
5. It will not have the correct colors
6. Repeat the above with the INI from "1.MoreComplex-Works-[Only added blank lines between sections]-copyq-DBAREIS-TOOLS-commands.zip"
7. It will now display with the correct colors

Note that I initially thought the INI handling needed these blank lines but I can make other non related data changes and get it to work which suggests some sort of in memory corruption of the INI object.

**Expected behavior**
The values in the INI should always be used.

**Version, OS and Environment**
(Get details from `copyq version` command if possible.)
- 6.1.0, neither "..\..\copyq version" or "..\..\copyq copyq version" works
- Windows 11

**Tried for a Very Simple Text Case but that worked**
