Multiple field notes on the same side of a class inherit the stereotype/color of the last note

When attaching multiple notes to different attributes of the same class, all notes on the same side of the class (for example, left) are rendered using the style/stereotype of the last note defined on that side.

using below plantuml:

@startuml
<style>

  .yellow {
        BackgroundColor #FFF3CD
        BorderColor     #FFEEBA
        FontColor       #664D03
        LineColor       #FFEEBA
        LineThickness   1
        RoundCorner 3
    }

  .red {
        BackgroundColor #fd0000
        BorderColor     #ff0000
        FontColor       #ffffff
        LineColor       #fc6060
        LineThickness   1
    }

</style>

class "Test 1" as test {
  Field1
  Field2
  method1()
  method2()
}

note left of test::Field1 <<yellow>>
yellow note left
end note

note left of test::Field2 <<red>>
red note left
end note

class "Test 2" as test2 {
  Field1
  Field2
  method1()
  method2()
}

note right of test2::Field1 <<yellow>>
yellow note right
end note

note left of test2::Field2 <<red>>
red note left
end note

class "Test 3" as test3 {
  Field1
  Field2
  method1()
  method2()
}

note right of test3::Field1 <<yellow>>
yellow note right
end note

note left of test3::Field2 <<yellow>>
yellow note left
end note

note left of test3::method1 <<red>>
red note left
end note

I would expect the "Test 1" notes to be red and yellow, but they are both red (they take the color/stereotype of the last defined note). I would also expect the two notes to the left of "Test 3" to be yellow and red respectively. Tested on online server. 

Observations:

• If the notes are attached to different sides of the class (e.g. one left, one right), the colors are rendered correctly.
• If two or more notes exist on the same side, they all inherit the stereotype/style of the last note defined on that side.
• Reversing the order of the notes causes all notes to adopt the new last stereotype, suggesting the renderer applies a shared style to a group of notes on the same side.
• The issue occurs both with custom stereotypes (<<yellow>>, <<red>>) and appears related to note placement rather than stereotype definition.
