BUG - Unselected Posterize value
When you choose 'Image / Adjustments / Posterize...' the 'Levels' value is not selcted by default.
We have either to drag the slider or click in the blank or else just hit the Tabulator button.
Without that step we cannot use numbers at once from keyboard to change the value.
In the CS2 that value was immediatelly selected when opening 'Posterize' palette.
In CS6 already not. So somewhere between these releases that had to be changed.
This bug was also reported to PreRelease / Windows 10 with CC 2020 (21.1.2)
