Inconsistent Image Loading When Switching Between Preview,Live,Edit Modes

Problem Statement

content returned by the API reflects the selected mode. However, there is an issue where images are sometimes displayed from a previously selected mode instead of the current one.

This suggests a race condition or incorrect execution order when setting the session variable that defines the active page mode. As a result, when switching modes:
• Images may load from the previously viewed mode instead of the current one.
• A user switching to Live Mode may still see an image from Working Mode if they had previously viewed that mode.
• Conversely, when switching to Working Mode, an image from Live Mode might still be displayed.

This behavior indicates that the API calls responsible for setting the session variable for the page mode might not be executed in the correct sequence or may be experiencing delays that lead to inconsistent caching or session states.
See:

Steps to Reproduce

1.	Open the page preview tool.
2.	Select Live Mode and observe the displayed images.
3.	Switch to Working Mode.
4.	Observe that some images might still be loaded from Live Mode instead of the expected Working Mode.
5.	Repeat the process switching between different modes (Draft, Edit, etc.).
6.	In some cases, images do not immediately reflect the newly selected mode but rather the previously viewed one.

Acceptance Criteria

Images should always load according to the currently selected preview mode.
• There should be no persistence of images from previously viewed modes.
• Switching modes should trigger a clear update of the images.
