Rectangular selection shows interval at line end when text is longer than screen

[SadFrobisher]

1. step1: input following code, the code length needs to be longer than window width
   select arandomtable1.id, arandomtable1.relative_flag, arandomtable1.randomcolumn1 from arandometable1 join arandomtable2 on randomtable2.relative_id = arandomtable1.id and arandometable.delete_flag = false join arandomtable3 on randomtable2.relative_id = arandomtable3.id and now() between arandomtable3.effective_start and arandomtable3.effective_end join arandomtable4 on randomtable2.relative_id = arandomtable4.id and arandometable.delete_flag = false and arandomtable2.another_relative_id = arandomtable4.id and arandomtable4.radom_column in ('random1', 'random2', 'random3', 'random5')
2. step2:start rectangular selection and continue draging to the right side when the horizontal scrollbar shows
3. step3:the interval appears in the line end
