Fixes #760

The bug is no longer present, but the sample provided is still super slow when switching items. Measured at 8 seconds. Need to fix that.

The slowness was due to changing the root type of items when switching out entire lists. See explanation here: https://github.com/fsprojects/Fabulous/issues/760#issuecomment-648321361
