P: Embedded Preview requires Develop setting change to build standard preview.

Attached video shows new issue with 13.5 and 13.5.1 since the "fix" for the automatically added white balance: as shot in the history.

With the update thumbnails in develop are resetting to the embedded preview and sometimes the white balance in the main image is not being updated until the user changes a value.

Video starts with me switching images and then hovering the mouse over the thumbnail of the last image which makes it reset to the embedded preview (icon reappears).

I then circle the bride's arm before adjusting the clarity slider a tiny amount and you can see the white balance updates.

Next I switch to the previous image and again hover over the thumbnail which switches back to the embedded preview.

Finally I switch back the other image and this time the white balance is shown correctly.

LRc isn't always creating a preview for an image when viewed in Develop unless the user changes a value. Sometimes it does but I cannot find a repeatable set of steps. I have tried clearing the Camera Raw cache with no luck.

Another thing I noticed is that when creating the video when I tweaked the clarity to -4 and back to 0 to force the white balance update a history step of: Clarity 0 0 was added - screenshot attached. Another bug?
