reduce left and right margins in popup dialogs
If you make use of a data-role="header" within popups, the popup heading will be abbreviated if it exceeds 40% of the available width (because the left an right margins default to 30%).
Eg., this happens in the "Delete Page..."-dialog example - small screen widths will abbreviate the title, even if there is still enough space to the left and right:

One solution would be to reduce the margin of h1-Tags in this case:

Hope this is a helpful idea...
