I think that I would take a different approach.  Instead of using the 
brute force method using the mouse motion event and selections in the 
html widget, use the html widget's ability to parse the content and 
notify you of where in the document you are.  The wx.html.HtmlWindow 
parses the doc into fragments called cells, and calls an overridable 
method whenever the mouse hovers over a cell, so you can derive a class 
from wx.html.HtmlWindow and implement a OnCellMouseHover method.  (Or in 
2.8 you can instead just bind a handler for the EVT_HTML_CELL_HOVER 
event.)  Something like this (untested):

class MyHtml(wx.html.HtmlWindow):
     def OnCellMouseHover(self, cell, x, y):
         # get the text of the cell and do something with it
         text = cell.ConvertToText(None)
         print text

There are also overridable methods for a cell being clicked, for a link 
being clicked, etc.
