switching editor causes loss of manual HTML markup

I want to make certain (external) links open in a new browser window or tab. To do so, I switch from my usually-preferred WYSIWYG editor to the "classic" wiki-markup editor and code the links using a target="_blank" ... -- works fine. I go back to working on the page with WYSIWYG editor. But when I change editor to "classic" again, perhaps to add another external link, my original HTML markup gets lost -- perhaps because the WYSIWYG-to-classic translator doesn't differentiate between WYSIWYG-created links and those marked up differently/manually. This makes the effort of adding HTML markup futile & frustrating. Can this be fixed?
