An extremely easy fix for this would be if they were to just actually make the feature of only having it happen on tab work. They have a setting for keyboard shortcut that can be set to either "Space or Tab" or to "Tab". If you could change that, and it would then only do this behavior when pressing tab, it wouldn't be that big a problem, but for me, despite having changed the setting to "Tab" instead of the default "Space and Tab" it still triggers when pressing space.
