"[]" (component with short form) does not work when "allow_mixing"

Question

Hello,

Same defect as https://forum.plantuml.net/10825/ but for component with short form [].

"When you want to mix several types of UML diagrams, you can add the word "allow_mixing" right after @start_uml.
But then declaring" component with short form [] "does not work anymore."

@startuml
allow_mixing
component foo1
component "foo 2"
[foo3 --> Does not work, with allow_mixing]
[foo 4]
["foo 5"]
@enduml

And :
