NOTE: Apply patch from D99 to avoid empty dropdown of internal pages.
# add `mode="inline"` to the 1st content block on homepage
# open website through the {nav Website & Content > Browse Site}
# go to `Content Mode` (link in top frame)
# write down link of each button in top frame (`Browse Mode`, `Content Mode`, `Design Mode`)
# write the `example text` inside content block
# select `text` word with a mouse
# click on the `Link` toolbar button (one that looks like a chain fragment) of the CKEditor
# select `Internal Web Page` as `Link Type`
# select `Products` page from `Internal Page Name` dropdown
# confirm, that links of buttons in top frame haven't changed (before this fix they were changed to page, that was selected in dropdown)
