Backpack Bug- blocks not fitting in window

blocks aren’t fitting in the window if they are longer in width (currently using it with zoom out (not convenient ) & collapsed blocks are not handy)
suggestion - add a horizontal scrollbar.

also, its logo(top-right) does not change to ‘filled’ even though there are tons of blocks inside.

this error is there for a long time, I thought it will get fixed by time,
hope moderator will look in
