IE11 Single page continuous scroll height keeps growing for unexploded epubs

[ghost]

This issue is a Bug

Expected Behaviour

Expected to open internal_link.epub in a single page continuous scroll layout while using IE11

Observed behaviour

opened internal_link.epub in IE11 (both running locally, and at https://readium.firebaseapp.com/?epub=epub_content%2Finternal_link.epub&). Scroll bar consistently shrank, memory usage increased, the scroll always jumped to the top. Console keeps reporting "OnePageView content resized ... X Y contentitem" where X is the width, Y the height (constantly growing), and contentitem is the current content item.

Problem doesn't show up on other browsers.

Steps to reproduce

1 - open Readium 2 - navigate to internal_link.epub 3 - hit settings 4 - select layout 5 - choose Format single page, and scroll mode continuous. 6 - watch the console for messages, and memory usage

Product

Choose one of the following (and delete the others)

• Readium cloud reader app
  • latest development build uploaded at https://readium.firebaseapp.com

Additional information

Not sure if this is a problem with the ResizeSensor, one_page_view.js, or scroll_view.js, or combination of the three together with IE11.
