Non-integer fps values cause frame preview thumbnails only being viewed for the first half of the sequence

Context

Studio name: Ryff
Kitsu version: 20.44
Production type: TV

Preview frame thumbnails not updating correctly if the source project's fps isn't an integer.

Running the mouse across the timeline to display the thumbnail preview results in only half of the frames being displayed (eg if the sequence is 140 frames long, 70 frames have the images, rest are blank). Small internal cross checks seem to be if the project's fps is a non-integer value eg 29.97, 23.976 etc instead of 24, 25, 30 which seem to be ok.
