Description
The case:
I have 2 simple text fields within a block. The second is hidden if the first is not empty (conditional logic).
The issue:
When I fill the first field (the second disappears), save the page and reload, then, after removing input from the first field and revealing the second one it occurs that the second field displays 0 instead of nothing.
It leads to many problems; for example, I spotted this issue when I had further conditional logic built upon the second field emptiness, failing with 0 value inside...
Related?
It may be related to #147 but I am not sure.

Research direction
Reproduce the described sequence: hide the second text field, save and reload, then clear the first field and inspect the revealed field's value. Trace the save and reload handling for conditionally hidden fields. Done means the second field remains empty and dependent conditional logic treats it as empty.
