Subject: [PATCH 07/40] Revert "Remove this piece of code"
This reverts commit bad007360a0f6fba304d8f4c99826a1250fd886c.
The lookup in the global object is necessary to detect whether we've seen any
unresolved properties. This is used for the optimization of skipping binding
refresh updates when a context property changes.

Subject: [PATCH 24/40] Revert removal of "Fixed MouseArea threshold with
preventStealing"
This reverts commit 9c8dab537819f0d999e680490c2d125b8836cbbb
where commit e1400b5b4d8311769ad3b9f631479ee2b0271197 was removed
due to the breakage of QtLocation tests.
After some hours of debugging it seems that the problem in QtLocation
was due to filtering of mouse move events in QDeclarativeGeoMapItemBase.
See QTBUG-52075

We need to evaluate the expression for the "with" statement that is supposed to

evaluation of the expression throws an exception - we'll try to pop the "with"
scope we couldn't open in the first place.

From 2ac19881f92c94f4e9427bd9ff513210675f259e Mon Sep 17 00:00:00 2001
From: Ulf Hermann <ulf.hermann@qt.io>

Subject: [PATCH 33/40] QML: Only release types if they aren't referenced
anymore
Just checking for references on m_compiledData is not enough. The
actual component can also be referenced. Thus it won't be deleted
on release(), but cannot be found in the type cache anymore.
Task-number: QTBUG-53761
Change-Id: I8567af8e75a078598e4fed31e4717134e1332278
