[WebView] Fix bug with right-click on selected link

This has been bothered me for a long time. Every time I right-click on a selected one-word link, only the link context menu would appear. Workaround was to select non-linked word or character (such as blank space) together with the linked word, but it would mean that unwanted characters are copied. With this fix, right-click on a selected one-word link displays correctly both link and text context menu.
