highlight of current line theme issue

[sidmint]

 * Xed version 2.4.2
 * Distribution - Mint 19.3

Issue
highlight of current line in "classic" and "tango" renders text unreadable as colour is too strong unlike other themes where colour is a very light shade.

Steps to reproduce
Toggle to highlight of current line from settings, select theme "classic" or "tango", read the current highlighted line where the cursor is.

Expected behaviour
Like rest of the themes, highlight colour should be a very light shade.

Those GtkSourceView themes are part of the library itself. We don't actually control them. Unfortunately some just do not work well with dark themes. The best solution in those cases is just to choose a different theme for the editor.

It's possible to tweak some colors by editing the files /usr/share/gtksourceview-4/styles/classic.xml and/or /usr/share/gtksourceview-4/styles/tango.xml and restarting the application.
