label-content-name-mismatch does not account for formatting markup

[curtbellew]

Rule label-content-name-mismatch doesn't seem to account for formatting markup. Example:

<button aria-label="button label">button<br>label</button>

Will return a violation.

Product: axe-core

Expectation: Formatting should be disregarded.

Actual: The string is compared directly so any HTML tabs present cause a violation

Motivation:

axe-core version: 4.1.3
axe-webdriver, extension or other integration version: X.Y.Z

Browser and Assistive Technology versions

For Tooling issues:
- Node version: XX  
- Platform:

Thank you for reporting this. I've confirmed the issue. I agree, this shouldn't be failing. We'll look at what we can do about this.

Validated with the latest axe-core dev branch code base,
for the test script 'button
label' , where label content is formatted markup, should not encounter the failure on label-content-name-mismatch rule.
Not seeing such failure, can find in screenshot
