Views Content Pane Exposed form in blocks don't use custom URL link displays

This issue was identified in the comments on #1417630: Exposed form in block doesn't redirect to right path even though I use inherit path . To recreate the issue, take the following steps:

• Create a view.
• Add a Page display to the view.
• Add a content pane display to the view.
• In the content pane display, add an exposed filter.
• Enable the exposed form in block setting.
• Set the link display to use a custom url and provide a new url.
• Create a panel page and add the exposed form in block you just created.
• Visit the page and submit the form. The form directs submissions to the page display in the view.

The patch that jhedstrom provides in comment #6 of that issue resolves this problem.
