Help text bubble size affected by component title length

[trymval]

Description of the bug

In Frontend version 4.4 or later, when a component's title exceeds a certain length, it adversely affects the size and formatting of the associated help text bubble. This issue was not present in earlier versions, such as v4.3.1.

Steps To Reproduce

1. Open an app using Frontend v4.4 or later
2. Create or edit a component and set its title to a lengthy string
3. Add a help text bubble to the component.
4. Watch as the help text bubble gets smaller as the title gets longer

Additional Information

A comparison of the rendered HTML between versions v4.3.1 and v4.4 shows changes in the class attributes of the help text button, from

<button class="fds-button-button-8fa00f0f fds-utility-focusable-1ed11112 fds-button-medium-8fa00f0f fds-button-tertiary-8fa00f0f fds-button-first-8fa00f0f fds-helptext-helpTextButton-f137834f fds-utility-focusable-1ed11112">
  <!-- Button Content -->
</button>

to

<button class="fds-helptext--md fds-helptext__button fds-focus">
  <!-- Button Content -->
</button>

... might suggest that the CSS classes responsible for the help text bubble's styling have been modified in v4.4?
