2016362 - Various issues on Coursera.org

Status: UNCONFIRMED

(Core :: DOM: Editor, defect)

Description

[caohfi7dh]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/145.0.0.0 Safari/537.36

Steps to reproduce:

1. Go to 'Coursera.org'
2. Enroll in the Microsoft Back-End Developer Professional Certificate
3. Go to ‘Guided Lab: Practical Coding with Copilot’ in the ‘Introduction to Programming With C#’ course in module 5

Actual results:

1. When you enter a long text and try to delete what you have written, confusion arises between what you have written and what you have typed on the keyboard.

2. Another problem encountered is that when you leave a tab with a video open and return to it after about 12 hours, all videos on Coursera will appear choppy.

Expected results:

1. I need to be able to enter text without overlaps or strange effects on the text that make it impossible to write.

2. Even if I leave a tab open with a video playing for an indefinite amount of time, I should be able to play the video without any lag.
