Zoom level distorted when reading file

[Poindexter Frink]

Saving and loading a file with a non-default zoom level causes zoom level to drift one level away from default.

Confirmed that this is happening during loading, not saving.

This bug leads to a further issue where Qt can no longer render the fonts due to excessive zoom out.

Raising priority.
