v6.3.0

New

Added a popup component(RichTextPopup) that can be used to edit the text in a freetext annotation to have different font styles such as bold, italic, underline, strike, or different colors.
Updated the search overlay to always be open while creating annotations. The purpose of this is to decrease the number of unnecessary searches.

Fixes

Fixed issue where the text and image panel of the signature modal was cut off when viewing in a portrait mobile device.
Fixed issue where in some cases custom loaderror event handler would be registered before the built-in handler.
Fixed issue where hotkeys were still enabled when the signature modal was open
