Unable to change the highlighting color via `highlight_color`

[davidhcefx]

Description

• According to your instruction, I should be able to change the highlighting color through the "highlight_color" config.
• However, setting it to any value failed to work. Including:
  • #fff
  • region.greenish
  • region.yellowish
• I discovered that every time I invoked Toggle Trailing Spaces Highlight, the config will be overwritten to "highlight_color": "region.redish"
• It seems that line 371 is doing something nasty.
  • Why do it need to change the user's settings? If it alter the user's settings, can it change it back? What if Sublime were exited before the changes being reverted?
