Autocomplete popup selects wrong item briefly

[techee]

Right now, Scintilla attempts to make the selection based on alphabetic sorting but we have autocompletion items sorted by some internal logic of the LSP server. While the plugin tries to select the first item in this list, the wrong item gets selected by Scintilla first which leads to some flickering:

Try to submit some patch to Scintilla to fix this problem.

Fixed in Scintilla, waiting for Geany Scintilla update.
