Test with WordPress 6.6 and PHP 8.3

I just ran the PHPUnit tests with WordPress 6.6 and they failed.

1) Tests_admin_oik_privacy_policy::test_oik_privacy_policy_options_do_page
Failed asserting that two arrays are equal.

Is this a problem with wpautop() or my PHPUnit test code?

• The problem occurs with WordPress 6.4
• The PHPUnit tests for oik work

Is this a problem with wpautop() or my PHPUnit test code?

This problem occurs when bigram is activated.

• The new filter function attached to render_block_ (for core/freeform) is invoked during the_content processing when processing the do_blocks filter function.
• the_content is invoked from oik_privacy_policy_preview().
• bigram_render_block_core_paragraph() uses the convert_bigrams_to_links method
• it uses process_contents() to find any links to convert.
• When it rebuilds the string, not all of the extra blanks that have been added after each tag's '>' character are removed.
• In the PHPUnit test case code the tag_break() method doesn't cater for these spaces so the test fails.

Workaround

• Deactivate bigram before PHPUnit testing oik-privacy-policy.
• Also ensure that the checkbox that oik-css provides to disable wpautop processing is NOT checked.

Fix

I tried changing both tag_break() and the bigram code, but this introduced other problems.

Then I realised I could add some logic in the affected test cases to remove the filter functions attached to render_block_. The test cases now run successfully regardless of the activation status of the bigram plugin.
