Admin sidebar menu item shows a 0.19px height difference causing slight spacing and alignment inconsistency.

[modi2918]

The WordPress admin sidebar contains a minor UI spacing issue where the .wp-menu-name element renders at 34.19px height instead of the expected 34px. This creates a subtle visual mismatch between sidebar menu items and the Collapse Menu button.

Actual Result
.wp-menu-name height renders as 34.19px.
Collapse Menu button height renders as 34px.
A slight spacing/alignment inconsistency appears in the sidebar.
Expected Result

All sidebar menu items and the collapse button should render with consistent heights and spacing using whole pixel values.
