page-down affects wrong panel in tabs

[Markorki]

When in display mode N°1 (explorer upper-left, thumnails in upper-right, preview/tabs in lower panel)

When using Exif, IPTC, or Exiftool tab, scrolling with the wheel of the mouse or upper/lower arrows of the keyboard works OK, but when I use "page down" ou "page-up" keys, the selected thumbnail changes in the upper-right panel, even if I click in the tabs panel; focus of these 2 keys keeps on the upper-right panel.
