Cursor falling behind in SQL Lab

When I type a SQL query in SQL Lab, the cursor doesn’t align with where I’m actually typing. This can be reproduced in Chrome, Firefox and Edge.

I suspect this is related to the following issues and MRs:

• https://github.com/apache/superset/issues/9095
• https://github.com/apache/superset/pull/9183
• https://github.com/apache/superset/issues/9253
• https://github.com/apache/superset/pull/9264

Since I can apply this fix manually in the browser to get it working.

Expected results

The cursor can roughly lines up.

Actual results

It doesn’t.

How to reproduce the bug

1. Go to ‘SQL Lab’
2. Type in your query
3. See error

Environment

docker pull apache/superset:1.2.0

This is still happening when running the latest, which is based off of 9c854ff1f1ab80b26438a3b6d91ca9b44b5f2a7a.

I think the root cause is similar to this: #9183 (comment). There are two .ace_editor classes applied to the SQL editor. Disabling the font-family attribute in one and having the font attribute in another applied seem to be able to get the cursor properly aligned.

Before:

After:

Chrome 102.0.5005.63 + superset 1.5.1 same issue here, and disabling the first font-family css could solve it.

@junlincc Sorry for the late reply and appreciate your help on trying to fix this issue so far.

Unfortunately, in my test just now with the latest image apache/superset:fcab489860399d38bc3a66fd26dd62b7c3e3ffd5, the issue still persists - could we please reopen this issue?
