V1.1.1
---------
 - Fixed highlighting of Markdown's single-line codes with multiple backquotes.
   Also, faster syntax highlighting for Markdown.
 - Prevented a rare hang-like behavior with malformed XML documents that have
   huge lines. Also, followed stricter rules for highlighting of \ 
"<" in XML.
 - Workaround for wrong positions of instant tab tooltips with Qt6.
