SUMMARY
The bar for typing a URL/PATH auto fills a recent directory permanently instead of it being a suggestion that can be selected with Tab.

In my specific case I wanted to use the sftp protocol, so I typed in sftp://, but it came out as Sftp://, because a recent directory I have previously typed in started with a capital S.

STEPS TO REPRODUCE
1. Have Dolphin remember a recent directory so it shows in the drop down menu of suggestions when using the directory path bar.
2. Continue typing a different directory and notice how the capitalization from the original suggestion remains.


OBSERVED RESULT
The wrong capitalization of a word will keep being fed into the location bar as long as a directory in "recents" shares the letters.

Example: subdirectory named "Androidstudios_install" will be autofilled as "AndroidStudios_install", because a directory in recents is called "AndroidStudioProjects".

EXPECTED RESULT
The auto fill will temporarily suggest a directory that you can select with tab but will not alter the location bar if you just keep typing in it.

ADDITIONAL INFORMATION
The capitalization might not affect something like the sftp URL from resolving, however it could disrupt a manually typed directory path because they're case sensitive.
