The task pane width is fixed and quite small in the browser version. Is there a way to programmatically set the default width on PowerPoint office js based addins?

And just a bit more context here: Due to the crippling limitations of the ribbon with Office.js (e.g., no nested submenus, no dynamic menus, etc.) and Dialogs API (e.g., no modal dialogs, no ability to customize the frame), add-in developers migrating their solutions from VSTO/COM are forced to move UIs to the task pane. Many such UIs do not fit neatly into tall, narrow task panes without exhaustive refactoring of the UI/UX that consumes a lot of man-hours. Therefore, having the ability to set pane width would greatly reduce the pain (pun intended) in moving from VSTO/COM to Office.js, and provide a better end user experience by not requiring users to manually adjust panes to the prescribed width.
