Detached HTLM/Style panel no longer has a window title

Not sure if this is really a “bug” per se, since it doesn’t seem to have any effect of the functionality of the program, but it may be important to the developers writing code. Version 5.5.1 of BSS used to display the window title “Editor” in the area circled in red (see attached image) when the window was detached. After I updated BSS to 5.5.3, I noted that there is no longer a title on the detached window.
