Starting in 2018, if the user is filtering in the File Dialog (using standard characters and/or wildcards), as soon as the user clicks a file in the filtered file listing, the filter is CLEARED.
This did not happen in 2017 and prior. The filter used to stay active no mater the file selection. It would only change if the filter itself was changed. With this behavior, the user could still multi-select, rename, etc files that were filtered to appear.
Please return this to Pre-2018 behavior.
