Display spinner for UI actions

[oleh-maikovych]

Description

Currently, all tg-ui-action elements that open a dialog containing an entity master do not display a progress spinner to indicate action execution. Due to slow internet connections, the dialog may take some time to open, which can make users think that something went wrong. Therefore, displaying a spinner would be very helpful to indicate that the action is in progress and that the dialog will open as soon as possible.

Please make the spinner visible for tg-ui-action elements that have a UI entity master as well.

Expected outcome

SA spinner should be visible for all tg-ui-action elements, regardless of whether they are UI or non-UI actions.
