With Bitbucket Forge apps, if we define page type modules, it only takes vertical space according to the content. This makes it challenging to create a responsive, mobile-friendly, or otherwise user-friendly layouts as app developers cannot predict when a scroll-bar will appear, and cannot add footer element at the bottom of their adminPage reliably.

In contrast page modules for Jira Forge apps take up the full size of the available space, enabling developers to position elements (like headers, footers, and sidebars) with consistent, predictable sizing.

Please make page type modules in Bitbucket behave the same as in Jira page modules. It'd be ideal if a prop can be added to toggle the behaviour.
