When clicking a button on a page loaded via a custom url handler, it may run into a render problem

When clicking a button on a page loaded via a custom url handler, it may run into a render problem as it will cause the page to crash. The message:

[5912:83971:1128/090904.147245:ERROR:bad_message.cc(25)] Terminating renderer for bad IPC message, reason 139

also appears. With the example, after it has loaded, click on the 2nd CSV button (further down the page).
