[FIX] web: click on button doesn't save

Problem:
In a list view, editing a record and then clicking an action button
on that record does not save the edited field values.

Expected behaviour:
Changes applied to the record must be saved before executing the button
action.

Solution:
The 46bd694c8a67f25470a911c1eb04e0bf2e17a5f7 commit in master solves
this problem (TaskID-3132960). We will backport it and add a test for
our use case.

How to reproduce:
- Go to a list view with one text field and one button action per record
- Edit the text field
- Click on the button action

Before this commit:
The value of the text field has been restored. We lost our modification.

After this commit:
The record has been saved.
