Misc UI Fixes (#1450)

* Fixed collection cover images not rendering

* added a try/catch on sending email, so we fail silently if it doesn't send.

* Fixed Go Back not returning to last scroll position due to layoutmode change resetting, despite nothing changing.

* Fixed a bug where when turning between pages on default mode, the height calculations could get skewed.

* Fixed a missing case for card item where it wouldn't show tooltip title for series.
