Problem:

We have 2 options to query: by filters and by TraceQL. 

When using TraceQL by clicking on Show Query, in case you enter an invalid statement and ends in an error, there is no way to recover from this unless you enter a valid TraceQL statement. 

So, in order to revert to see the filters again, I should leave Traces page and back again to reset the error state.

Steps to reproduce:

1. Go to Observe > Traces
2. Click on Show Query link
3. Enter { 1 }
4. Click on Run query => error is presented
5. Hide query link is disabled
6. I am locked in this error state and I am not able to cover from it by using the filtering again.

Expected Result: There should be a way to recover from error state with some initial state, without forcing me to know a valid TraceQL to solve the problem.
