This avoids an issue in clang-cl on Windows ARM64 where an invalid pointer would be (re)used. See #124182 for more details, but basically without this, when the vector of tiles inside changeset is resized, a reference to an invalid pointer (ie, the location in the old vector) is kept somewhere, which makes the test fail.
