Bug in class diagram member to member connection if naming is similar and contains underscores (since version 1.2022.0)

I encountered a bug in class member to member connection functionallity when updating from version 1.2021.16 to 1.2022.6. A few diagram lines from member to member had lost their connections. They don't attach properly anymore. I reverted the version back to 1.2021.16 where everything works fine. A test with all newer versions 1.2022.x showed that the point of failure is from 1.2021.16 to 1.2022.0.

To give an example of the broken diagram:


left to right direction
skinparam nodesep 80
skinparam ranksep 200
skinparam ClassAttributeFontSize 16
skinparam arrowThickness 3
hide empty member

!define my_red FF0000A0
!define my_blue 0000FFA0
!define my_green 00AA00A0

package "SAMPLE_1" as pkgsmp1 {
    package "SAMPLE_2" as pkgsmp2 {
        class "BigLibrary" as lib {
            + function_a()
            + function_b()
            + long_named_function()
            + long_named_function_but_different()
            + long_named_function_also_different()
            + more_functions()

    package "DIFFERENT_SAMPLE" {
        class "SomeHandler" as handler
        class "SomeHelper" as helper
        class "SomeParser" as parser

handler -[#my_red]- lib::function_a
handler -[#my_red]- lib::long_named_function
handler -[#my_red]- lib::long_named_function_also_different

helper -[#my_blue]- lib::long_named_function_also_different
helper -[#my_blue]- lib::long_named_function_but_different

parser -[#my_green]- lib::function_b
parser -[#my_green]- lib::more_functions
parser -[#my_green]- lib::long_named_function_also_different
parser -[#my_green]- lib::long_named_function


On 1.2021.16 all lines are connected properly. On 1.2022.0 lines connected to "long_named_function_xxx()" break.

Any chance to get this fixed or working again?

Thank you in advance!
