[BasicUI] Switch items’s values can go out of screen

[dilyanpalauzov]

I define two items

Switch a
Switch b

a map transformation openhab/transform/b.map

ON=0 1 2 3 4 5 6 7 8 9 A B C D E F G H I J K L M N O P Q R S T U V W X Y Z a b c d e f g h i j k l m n
OFF=a b c d e f g h i j k l m n o p q r s t u v w x y z 0 1 2 3 4 5 6 7 8 9 A B C D E F G H I J K L M N

and a sitemap:

sitemap a label="A" {
  Text item=a
  Text item=a
  Switch item=b label="I am soo good switch [MAP(b.map):%s]"
  Switch item=b label="I am soo good switch [MAP(b.map):%s]"
}

When I set a value for b, use three columns for rendering, and then load the sitemap, on the first load in the first line the toggle is not shown in the view port:

Once I switch the toggle, the toggle on the first line is shown, but everything moves to the left and then the start of the line is not visible.

Both screen shots above show area left and right - that is outside - of the browser. There are no horizontal scrollbars.
