Steps to reproduce:

1. Open any jsp page in VPE editor and select some text in VPE source pane. The same text is selected in visual pane.
2. Make mouse left click somewhere in visual pane. There should be no selected text.
3. Select the same text in step 1. via source pane
4. No text is selected in visual pane but the same text selected in source pane has to be selected in visual pane.

After reopening jsp page it's working again as mentioned above. Selection is synchronized only first time.
