Content--after-open has extra styles in Safari 14, It does not work properly because of this

[myas92]

Summary:

Modal does not work correctly because there is a value for left, right, and bottom properties in Safari14, everything is correct in Safari 15

Steps to reproduce:

1: In the initial modal there is some value for the top, right, left, and bottom so the result is like the below photo

2: when I remove the values from the right, left, and bottom my problem is solved

Expected behavior:

• Why is everything okay in Safari 15 as seen in the photo below?

• What is the best practice to solve this problem in Safari 14 and reach to the same result in every version of Safari?
