Description of the bug

scroll silently fails to render child when its parent has :space-evenly false, no errors posted into eww logs, scrolledwindow appears in eww inspector also as expected but nothing appears on the widget

Reproducing the issue

(defwidget somewidget []
    (box
        :orientation "v"
        :space-evenly false
        :spacing 5
        (label :text "some text" :style "...")
        (scroll 
            (box
             :orientation "v"
             :space-evenly false
             :spacing 5
             (entry :str "${hostname.Hostname}" :img "./thing.png")
             (entry :str "${hostname.KernelName} ${hostname.KernelRelease}" :img "./thing.png")
             (entry :str "${hostname.Hostname}" :img "./thing.png")
             (entry :str "${hostname.KernelName} ${hostname.KernelRelease}" :img "./thing.png")
             (entry :str "${hostname.Hostname}" :img ",/thing.png")
             (entry :str "${hostname.KernelName} ${hostname.KernelRelease}" :img "./thing.png")
            )
        )
    )
)

Removing the "some text" label doesn't fix the issue, only making the main child box of the widget :space-evenly true fixes the issue

Expected behaviour

The entrys should be displayed normally

currently it looks like this:

if :space-evenly true is set for the parent widget it looks like this and scrolls as expected

Additional context

No response

Found the problem, the scroll widget needed a specific height to be set when :space-evenly was set to false.
