Cursor moves in text edit

After validation fails in a text edit, you cannot click to move the cursor to edit the field. Instead you must completely delete the entry and start over.

If you try and click anywhere in the text box, the cursor is always moved to the end of the text.

see https://github.com/esnet/esnet-esdb/issues/799

Start by reproducing the text-edit behavior after validation fails, using the issue description and the linked esnet/esdb issue for context. Trace the text box handling from the relevant entry point you find; done means clicking within the existing text places the cursor at the clicked position instead of always moving it to the end.
