Steps to Reproduce:

1. Initialize readium
2. Read any epub of size more than 1MB
3. Increase the font size inside the reader by updating the settings
   Below is the code snippet:
   • Initial fontSize = 100
   • On font increase = font size +10
   • On font decrease = font size - 10
   • readium.reader.updateSettings({"fontSize": fontSize)

Observation:

Application terminates with the memory warning error

This is works fine in Android devices and chrome browsers. This crashes only in the ios devices. I have tried with both develop and release0.14 readium versions. Any suggestions you can provide for cleaning up the memory/Turning off the events before increasing the font size.

Verified with 0.23 that this no longer occurs.
