Log/Capture: fix capture to work on clipped child windows.

+ Tweak ErrorCheckEndFrameRecover() to use local window pointer.

@@ -78,6 +78,7 @@ Other Changes:
 - Fonts: Updated GetGlyphRangesJapanese() to include a larger 2999 ideograms selection of Joyo/Jinmeiyo
   kanjis, from the previous 1946 ideograms selection. This will consume a some more memory but be generally
   much more fitting for Japanese display, until we switch to a more dynamic atlas. (#3627) [@vaiorabbit]
+- Log/Capture: fix capture to work on clipped child windows.
 - Misc: Made the ItemFlags stack shared, so effectively the ButtonRepeat/AllowKeyboardFocus states
   (and others exposed in internals such as PushItemFlag) are inherited by stacked Begin/End pairs,
   vs previously a non-child stacked Begin() would reset those flags back to zero for the stacked window.
