CXTPToolTipContext::FilterToolTipMessageHelper does not seem to handle TTF_ALWAYSTIP correctly.

If you create a CXTPToolTipContext in a popup window, the tooltip never shows if the popup has the focus and not the parent / application main frame.

The CXTPToolTipContext::FilterToolTipMessageHelper correctly checks for the TTF_ALWAYSTIP in line 2198:

if ((tiHit.uFlags & TTF_ALWAYSTIP) || bTopParentActive)

to determine if a tooltip should be displayed.

But in line 2045 it does not check for that flag and destroys the tooltip if the parent is not active:

BOOL bTopParentActive = CXTPDrawHelpers::IsTopParentActive(pWndHost->GetSafeHwnd());

if (m_pToolTip->GetSafeHwnd() && m_pToolTip->IsWindowVisible() && !bTopParentActive)
...

this cannot work, right?

But I needed this in my product now and it works.

Mentioning here so that it can help someone.
