Incorrect highlight python decorator

[PavelBlend]

Description of the Issue

The decorator color is not yellow if it contains a dot.

Steps to Reproduce the Issue

Paste this code into Notepad ++ 7.7.1 32 bit:

import test_module


@test_module.test_decorator
def test_function():
    pass

Expected Behavior

The entire decorator should be yellow.

Actual Behavior

npp uses scintilla as its core lexing component and therefore issue needs to be reported here.
From my limited understanding it seems the issue is here.
If I replace this with if (!IsAWordChar(sc.ch, options.unicodeIdentifiers)) { then it seems to work.

I wrote an issue to lexilla and got the following response:
ScintillaOrg/lexilla#219 (comment)

Is it possible to fix this in Notepad++?

@donho It seems there are new problems with the decorator.

Class method decorators have the wrong color:

Like I tried to explain before, there are two different lexer properties to configure.

The function decorator is in the SCE_P_DECORATOR state (id=15), which already has a style associated with it by the default Notepad++ theme.

The method decorator is in the SCE_P_ATTRIBUTE state (id=20), which does not yet have any style associated with it.

Here's how it should look in SciTE with both options configured:

; %UserProfile%\SciTEUser.properties

lexer.python.decorator.attributes=1
lexer.python.identifier.attributes=1

; decorator style
style.python.15=fore:#FF8000,italics,bold

; attribute style
style.python.20=fore:#CD0000,italics,bold,underlined

@donho I expected different behavior. I have a standard theme. Decorators look like this:

I added a new ATTRIBUTES color to the stylers.xml file. This is the result:

I would like to have such a result:

Is it possible to specify the color of decorator attributes separately from other attributes?

I want to get the same result as functions:
