Bug ID: 42939
Summary: VisualEditor: Save button should be disabled if dm
state is identical to page when it was loaded
Product: VisualEditor
Version: unspecified
Hardware: All
OS: All
Status: NEW

Right now, the Save button starts disabled, but when the transaction depth is
non-zero it's enabled. This means that two actions that reverse each other
(rather than being formally undone) let the user make a 'null edit', which MW
then silently accepts.
Ideally, the Save/Create button should be disabled if dm state is identical to
page when it was loaded (except for the special-case of oldid pages, where it
should always be enabled). Roan suggests a string comparison of the current and
original HTML is the least-bad option, given the lack of hash functions in
JavaScript.
