Thanks for finding that bug, we are looking into it. The landscape load screen is not required to make your build. We will work on getting this working again.
If this is purely for displaying information and has no actions triggered by tapping the text you could use a texttemplate. In wire there is no concept of an inline element like a span or b tag, everything is block. Basically you would turn it into html then you could write some css to style it. This will not work if you need this to be a button because you cannot put an onclickup, onclick, etc because the web view will not know how to distinguish a link or another tap. Although you could put another panel over the web view that has the onclickup if needed.
You could put an empty panel that is only a few pixels wide with no background color centered in your container and give it an alias. You could then use leftof and rightof to position around it.
When you are adding or changing links on a pdf in the Preview app it is important to include the "http://" on every URL. The hyperlinks will not work if the protocol is missing. Also, if you are editing page links or hyperlinks make sure that after you have made a change check the top of the Preview where the name of the file is, it should say "edited". If not then resize or move the link box slightly until it does say edited. If it doesn't say edited, it doesn't see it as a change and will not save your changes. Believe me, I have had to redo pdf links on a 90 page pdf 3 times because I didn't know about the "edited" state.
