Issue description

The : character is not correctly escaped in a string. When it's followed by a abstract function (who does not have an ending :.

Inside Godot Script Editor: (it's ok)

There is the same issue in the VScode extension and in Github preview.

Not working version

@abstract
func _get_display_name() -> String

func _get_property_fullname(property: StringName) -> StringName:
	return StringName("%s:%s" % [_get_instance_name(), property])

func messed_up_func() -> void:
	prints("Everything here is broken")

Working version

func _get_property_fullname(property: StringName) -> StringName:
	return StringName("%s:%s" % [_get_instance_name(), property])

func messed_up_func() -> void:
	prints("Everything here is OK")

About the Github broken part I don't know where to report it if anybody can point me a direction.

Steps to reproduce

Create a script with the following code:

@abstract
func _get_display_name() -> String

func _get_property_fullname(property: StringName) -> StringName:
	return StringName("%s:%s" % [_get_instance_name(), property])

func messed_up_func() -> void:
	prints("Everything here is green")

I'm seeing a lot of syntax highlighting breakage after declaring an abstract function in any script. After the first @abstract, following @abstract decorators as well as argument parameters seem to lose their syntax highlighting. I'm wondering if the lack of a trailing : in abstract func declarations is tripping up the highlighter?

I ended up using highlight extension (https://marketplace.visualstudio.com/items?itemName=fabiospampinato.vscode-highlight) with config similar to this:

"(?<!\\w)(@abstract)(?!\\w)": { "filterLanguageRegex": "gdscript", "decorations": [ { "color": "#ebc47c" } ] },

@salandered caused by the func abc()
function_declaration expects to end on a :

@abstract
@abstract func set() : void
@abstract
@abstract func set() -> void
@abstract
