Search Block: Opening/closing the input field action change the height when "Button only" style

[t-hamano]

Description

When the Search block is Button only style, the input field is not displayed, but is made visible by clicking the button, and hides when it loses focus.

If a button has multiple words, the button text will unintentionally wrap when the input field is displayed.
As a result, the height of the block will fluctuate when the input field is opened and closed.

I believe that unless the user explicitly breaks the button text, the text should not wrap.

Step-by-step reproduction instructions

• Add a Search block.
• Apply "Button only" style.
• Update button text with multi-word text. (e.g. Search for posts)
• Click the button.
• The button text should wrap and increase in height.
