break arrow gets broken

Question

Everything is ok in the following example:

@startuml
start

while (data?) is (yes)

    if(bad data?)then(yes)
     break
    else(no)
     :process;
    endif

endwhile (no)

stop

However, if you add more lines of text into the "then" statement, the "break" arrow gets broken:

@startuml
start

while (data?) is (yes)

    if(bad data?)then(yes\nnew lines\nbreak the arrow)
     break
    else(no)
     :process;
    endif

endwhile (no)
