min size and variable width

Hi! I have an issue related with the splitter, in my project i have a splitter with 3 areas (horizontal) in my screen but at the first load when the screen width its too small, the min size that I want is ignored and the actual size that its rendered its less that i expect so the min size value that i set on the code only works when the splitter is resized, i don't know if there is a way to prevent this. 

function getPaneOptions(element) {
   return {
       collapsible: element.attributes['pane-collapsible'] ? true : false,
       size: element.getAttribute('pane-size') || '250px',
       min: element.getAttribute('pane-min-size') || '200px'
   };
}
