Messages Window, unexpect mouse click result when scrolled

• Lazarus/FPC Version: 2.3

Wenn the messages window

• has multiple sections (after compiling),
• and at least 2 sections are shown, so that the top one is partly scrolled out.

The the top section is only showing its header, and below that some of its lines, the other are scrolled out.

Now clicking the header, will not select the header, but instead select (and jump to) the invisible line that is "hidden" behind the header. (the header will then be hidden, and the line shown).

Clicking on a visible item, should not act on something invisible.
