Description:
Sometimes SQL Editor tab is executing queries on different schema that is bolded (selected) in the schema list pane. The problem is very big, if you have for example a lot of schemas on single instance that differs only in schema name, you can accidentaly execute query on wrong schema.

How to repeat:
Can't find correct steps to reproduce it, but I very often switch active schema, through: use _schema_name;

i forgot to mention that such bug didn't exists in 5.2.44

topic letter mismatch fix

few more things, 
if i issue use _schema_name; and after that issue: select database(); i got correct active schema. If after that i leave wb and do something else then issue in wb again: select database(); the active schema is changed :(, it looks like something in the background is changing sql editor active schema, but the schema list in the left pane is untouched , so if you will not check the active schema by select database() you can exec query on different schema :/

more: schema is chaning every 3-4 minutes, and in my case it's always falling back to the first schema that is visible in the schema list pane

to reproduce the bug, use these steps:
set wait_timeout = 180;
set interactive_timeout = 180;
use _some_schema_name;
select dabase();
wait 4 minutes
select database(); //voila different active schema

Just restart the server and issue the "select database()" query again. This will show a different schema then.
