Mobile: Long dialog titles cause the generic dialog components to extend beyond the screen dimensions on mobile view

[ianyong]

The generic ConfirmDialog and PromptDialog components both suffer from this issue, which affects all existing dialogs where the title is fairly long.

A similar issue can be observed for each of the assignment blocks, where the title, "Finalise Submission" and "Review Submission" cannot be seen.

Similar issue with the "Text Search" and "Index Search" search bar for SICP JS
