Simple Request, 28+ Minutes of Processing and Additional Tasks

What version of Codex is running?

OpenAI Codex (v0.55.0)

What subscription do you have?

Teams Pro

Which model were you using?

GPT-5

What platform is your computer?

Microsoft Windows NT 10.0.26200.0 x64

What issue are you seeing?

I asked Codex to format two dropdowns in a similar fashion to one of my other HTML pages as well as change their behavior to pop up and drop below the line instead of above. This usually takes about 3-4 minutes, it went on to do all sorts of other tasks I didn't correct and ended up taking over 28 minutes from this prompt "nice job, now can we format these dropdowns like those in timesheet.html and make them default to popping open in a
down direction and not up?"

What steps can reproduce the bug?

Asking it this question in my context "nice job, now can we format these dropdowns like those in timesheet.html and make them default to popping open in a
down direction and not up?"

Example.txt

What is the expected behavior?

3-4 minutes of reviewing the example sheet and then making changes to the two dropdowns I was targeting.
