Unnecessary Confirmation Dialog

[VitorVieiraZ]

A confirmation dialog appears when navigating back on unchanged, read-only layers. To reproduce: open one feature form, hit back (no confirmation), then open a second feature's form—subsequent backs trigger the confirmation. A binding loop is observed from the second feature form onward and may be contributing to this issue.

This is two bug in a trench coat :

• One in Mergin Maps where the way we constructed the form dialog didn't trigger the function to check for changes, should be fixed in Fix uneccessary confirmation dialog when reopenning a form #3690
• The second is directly in QGIS and mutiline form using the is html checkbox, QGIS (or maybe Qt) insert a boiler plate html code to simulate richtext editing, thus creating a difference if the field was simple text before and trigger the save dialog. But once the field is saved again in html it should be good.
