P: Removing flag happens to next image when moving quickly

When viewing a film strip which is filtered to only show flagged image if I click on the flag to "unpick" the selected image and then click on the next image that image is also unpicked. It's a little complicated to explain but the attached video shows it happening and it's very easy to duplicate using these steps:

Set the pick flag on multiple images
Go to Develop

Filter only so only images with the flag are displayed
Select an image
Click the flag on the thumbnail to remove it from the filtered list
Quickly click on another thumbnail
A second image will be removed (UNDO will return it)

It seems like the time it takes for the preview for the next image that's automatically displayed when the last image is filtered out is the window for when a click on a thumbnail means the 2nd image will also lose it's flag.

I believe it's a bug, it's been happening for quite a few versions now but I've posted in discussion as per the preferred method of reporting. It's become more apparent and annoying in 14.3 because of the longer time taken to switch and display an image increasing the time when it can be triggered.
