NO

Description

In the Posts, media pages there is an inconsistency in the left padding between buttons (e.g., "Add Media File", "Add Post", "Apply", "Filter") and the select dropdowns (e.g., "Bulk Actions", "All Categories", "All dates").

Screenshots

Button Before

padding : 0 12px i.e. padding-left will be 12px

Select Before

padding: 0 24px 0 8px;

Select After

padding: 0 24px 0 12px;

Expected Behavior

Both buttons and select dropdowns should have consistent left padding for better visual alignment.

Actual Behavior

The select dropdown has 8px left padding while buttons have 12px left padding, causing text misalignment when these elements appear side by side.

Proposed Solution

Update the left padding of the select dropdown in /wp-admin/css/forms.css from 8px to 12px to match the button padding.

Tested:

WordPress: Playground and 7.0 RC-2 both
OS: Ubuntu 24.04
Browser: Version 146.0.7680.153 (Official Build) (64-bit)
