SQL command partially broke in Opera 12 since Adminer 5.0.6

[TCH68k]

Adminer version: 5.0.6
Compiled: Not important.
Driver: JS (syntax highlighter)
Database version: Not important.
Plugins used: None.

In Adminer 5.0.5 the SQL command worked perfectly in Opera 12, but in 5.0.6, it partially broke. The syntax highlight is gone, but the even bigger problem is, that when executed, Adminer reports that there are no commands to execute. The debugger reports no JS errors.

Workaround: Disabling JS makes it work.
