Hello, and one more problem I found:
When I use some block of code:
the palette is shown not correctly, since it's positioned with "position: absolute" and since it's placed inside "position: fixed" block, its "top" value means it shifts relatively to top left corner of parent block.
So if I place the parent element at "bottom: 0", the picker is shown far far below the bottom browser window border.
So, I have to go via DOM (or with styles) to define some other "top" (and, possibly "left") position for the picker palette element to solve the issue.
