Below 100 % ElementView::drawBackground() hid the grid and also set the snap step to 1 unit, so anything dragged while zoomed out landed off the grid with nothing on screen to show it. A large symbol opens fitted to the window below 100 %, which is why the report also says "when the selection is big". Keep hiding the grid below 100 % (its dots would merge into a grey wash), but snap every 10 units, as at 100 %. The zoom-to-grid rule moves into a header-only ElementViewGrid so it can be tested without an editor window, like textgrid.h. Checked in the editor: a one-rectangle symbol zoomed out to about 0.6x, its edge dragged by (15, 10) px and saved: master moves it by (28, 18), this branch by (30, 20). tst_elementviewgrid fails with the old step 1 and passes now; ctest 45/45.
