that is strange. What keys are you using to navigate to these links, are you using tab or up and down arrow keys?  I have almost the same type of thing happen when I use the twitter website with microsoft edge.  When reading tweets the reply retweet etc buttons will all be read as one chunk making it impossible to hit enter on them. The way I get around it is, I use left and right to get to the button I want than I press enter and that works. Maybe you should try that for your problem. Hope it helps Ken
