tdf#154565 ignore unwanted crossing event from search to treeview on "enter"
i.e if the crossing was triggered ultimately by a key stroke which is
likely from exiting the search box.
This way we can avoid the problem that with hover-selection that after
"enter" is used in the search box, selecting a matching row, then during
teardown of the widget the box is hidden, and the generated crossing
notification triggers unwanted selection of a different row under the
mouse.
If needs be this could be refined further to only happen for a specific
key or other details of the triggering event
