To change arrow layout direction is required if any arrow flows back to a component in front.
Example: Second2 --> First
@startuml
top to bottom direction
rectangle "First" as first
rectangle "Second1" as s1
rectangle "Second2" as s2
rectangle "Second3" as s3
rectangle "Third1" as t1
rectangle "Third2" as t2
rectangle "Fourth1" as f1
first --> s1
s2 -UP-> first
first --> s3
t1 -UP-> s1
s2 --> t2
t1 --> f1

The same is true if someone uses
left to right direction
Bug:
Using "left to right direction" in combination with arrow LEFT, RIGHT, UP, DOWN is not rendered correctly.
I want to achive this:
with this code:
@startuml
left to right direction
rectangle "First" as first
rectangle "Second1" as s1
rectangle "Second2" as s2
rectangle "Second3" as s3
rectangle "Third1" as t1
rectangle "Third2" as t2
rectangle "Fourth1" as f1
first --> s1
s2 -LEFT-> first
first --> s3
t1 -LEFT-> s1
s2 --> t2
t1 --> f1
@enduml
But need to use this one:
@startuml
left to right direction
rectangle "First" as first
rectangle "Second1" as s1
rectangle "Second2" as s2
rectangle "Second3" as s3
rectangle "Third1" as t1
rectangle "Third2" as t2
rectangle "Fourth1" as f1
first --> s1
s2 -UP-> first
first --> s3
t1 -UP-> s1
s2 --> t2
t1 --> f1
@enduml
If I would use "LEFT" as expected, the rendering would be:
Thanks for help,
