steps to reproduce

1. run the attached file, 3458.zul

actual result

There is an extra space between the right side of the window and the right edge of the page.

Since we specify hflex="1", the window's width should extend to fill the page's width.

expected result

There should be no space between the right side of the window and the right edge of the page.

debug info

1. overflow.zul is the user's original case
2. resize a browser's width, the window's width will fill up the page's width

workaround

• If you use modern browser that supports css flexbox , you can specify flex-grow on the window e.g.

      <style>
  	.flex{
  		flex-grow: 1;
  	}    
      </style>
  <window contentStyle="overflow: auto" sclass="flex">
  

• specify width="100%" on parent components.
