Is Issue Present in Latest Beta?

I'm not going to check this.

Description
I have 1000 lines of queries in the Query tab editor. For a long time leading up to this point, even when I only had 300 or 500 lines in the editor, whenever I typed the character ")" (or "("? can't remember exactly), the editor would lock up for a second or two. The amount of time it locked up increased with the number of lines I had in the editor, up to the 10-15 seconds it is today. I finally turned off bracket highlighting today and there's no issue with it off.

Steps To Reproduce

1. Have 800 lines of queries and bracket highlighting on.
2. Type ")"

Expected Behaviour

Editor is responsive.

I find a similar result just clicking after ( when the query is large.

Likewise, turning off Bracket Highlighting entirely fixes the issue.
