💡 Background and solution

When placing a few components inside of a <Space /> component, I noticed that they were not aligning properly. Here is the code in question

<Space>
  <Button><Icon name='cog' /></Button>
  <Divider type='vertical' style={{ height: '32px' }} />
  <Radio.Group
    optionType='button'
    options={ ['ON', 'OFF'] }
    defaultValue='ON'
    size='middle'
  / >
</Space>

This resulted in a slight vertical misalignment of UI elements

I did some digging and discovered the culprit to be an unnecessary line-height declaration in the <Radio /> component. Further investigation revealed that this was introduced in a RTL PR (#19380). I removed the extra line-height and verified layout in LTR and RTL.
