Clone dialog: Dir/Web button is confusing

In the Clone dialog, there's a button at the right side of the first text box. It reads "Dir..." or "Web". The text of the button can be changed from the dropdown menu at the right end of the button. But whatever I select here, clicking the button itself doesn't do anything at all. I'd expect a browse dialog or something, but nothing happens.

The button is visible but not mentioned in the help document.

Version 1.8.15.0

Update after some discussion:

That button is supposed to let me browse a local filesystem directory when I have entered a local path in the text box. There is a problem with that however: It does nothing if the path does not exist as-is. If the path does not exist, the folder browse dialog should open anyway, preselecting the closest directory from the entered path that exists.

Then, the button is supposed to open the entered URL in a web browser if it's a URL. This is an entirely different meaning. It doesn't let the user choose what to enter, but instead it displays more info about what was already entered. The data flows in the opposite direction here.

Moreover, the button is a split button that lets the user select from "Dir" (select local folder) or "Web" (open URL in web browser), but actually this action is determined by the type of text entered and cannot be chosen by the user manually.

So, additionally to the partial path dialog above, the button should not be a split button but always change its text depending on whether a local path (local drive or UNC path) or a URL (http/https) was entered. And the button texts should be changed to

• "Browse" for local paths
• "Open web browser" for URLs
