type to select doesn't update

re #64727

• get changes in joh/o2
• start typing in the outline view
• on first type the selection updates
• on subsequent types the selection doesn't change to the better match

this only seems to be an issue with the sync tree, the async data tree that I use in breadcrumb file pickers does work fine

Actually this happened for all trees. Repro:

1. Create foo and foobar files in Explorer
2. Type foo, foo should be focused
3. Type b to get foob, foobar should be focused and isn't
