Description

Prerequisites
Describe the issue

If you create a progress bar where the progress is not very far (ie 0%) the inner descriptive text will not be displayed.

<div class="progress">
  <div class="progress-bar" role="progressbar" style="width: 0%;" aria-valuenow="25" aria-valuemin="0" aria-valuemax="100">I want to be seen!</div>
</div>

This has come up before. Most recently(?) it was https://github.com/twbs/bootstrap/issues/24538 (fixed for 4.0 release).

As shown below with the test cases the issue where text will not display appears to have been introduced via 4.4.0.

Reduced test cases

This issue can be seen in the current bootstrap (5.2.3)

I did some looking at older versions of bootstrap and this appears to have been working in 4.3.1

But not the 4.4.0 release

Research direction

Start with the reduced test cases and compare the progress bar behavior in Bootstrap 4.3.1, 4.4.0, and 5.2.3. Trace the progress-bar styling responsible for hiding or clipping inner text at 0%, then verify that the descriptive text remains visible in the reported example without regressing other progress values.
