Ionic 3 using Stackblitz IDE - Modal Resize Issue

Need some help on an Ionic 3 project. Issue is with resizing modals to occupy 90% of the screen height and width. Need solution to work off Stackblitz online IDE. Link to test : [login to view URL] Click on open in new window to see project in a full browser window. Issue : Image 1 - In full screen browser, the model appears in a restricted size, does not fill browser window. Image2 - If browser window made full width and 80 percent of screen height then OK, modal expands, if I make browser window height a bit more, modal switches to Image 1, modal in a restricted space. Image3 - If browser window made full height and 50 percent of screen width then OK, modal expands, if I make browser window width a bit more bigger (than shown on image), modal switches to Image 1, modal in a restricted space. Expected Results : The modal should fill up the screen when browser is full screen, not be in a confined box, solution needs to be implemented on Ionic Stackblitz IDE. Only reply if you have a solution and it works on Stackblitz IDE. Thanks Sugan
