title: SAPUI5: sap.m.TextArea cursor position
body: <p>I'm using sap.m.TabContainer with items containing sap.m.TextArea's. If I switch between tabs,
  the cursor position in the textarea's is reseted. I would like to keep the cursor position in the textarea's. Is there a possibility to store the current cursor position bevor leave and set the stored position on enter of the textarea?
