First of all, Happy Holidays, .
Right-clicking in the pop-up window (Scan Pop-up feature enabled) selects the nearest word about 1.5-2 cm down. In the picture attached, I right clicked the empty area alongside the bold "group" header, and the program automatically selected a word below. This makes it impossible to precisely right-click a word one needs to. Right-clicking in the main window works as intended.
Besides, you may notice in the screenshot that the "Copy" string is not translatable yet. You may want to add it, together with "Close Tab".
