[Close #16502] Clarify the bs-callout on multiple open modals
Currently it states overlapping modals, this isn't the only case as this truly applies to any instance when a user would want to open multiple modals at the same time. For this reason, I have modified the title of the callout to make this more clear.
<p>Modals are streamlined, but flexible, dialog prompts with the minimum required functionality and smart defaults.</p>
<div class="bs-callout bs-callout-warning" id="callout-stacked-modals">
- <h4>Overlapping modals not supported</h4>
+ <h4>Multiple open modals not supported</h4>
<p>Be sure not to open a modal while another is still visible. Showing more than one modal at a time requires custom code.</p>
</div>
