Holding query in the text Area in case Query is not executed.

**Observation**: The query should not be wiped out from the text Area when the query is not executed i.e. when there is an error. It is quite annoying to write or copy queries again and again in the text area while drafting the correct query.
**Possible solution**: It can be stored in the Local Storage of the Browser and can be redrafted in the text area in case of error.

As in the following example: I will have to rewrite the query or copy it from the new tab rendered.
