PHP 8.x deprecated function warning at runtime

My apologies, two of the errors are fixed. I've updated the issue summary. I am still seeing this code in the latest dev version of plugins/views_plugin_style.inc starting on line 151:

  /**
   * Take a value and apply token replacement logic to it.
   */
  public function tokenize_value($value, $row_index) {
    if (strpos($value, '[') !== FALSE || strpos($value, '!') !== FALSE || strpos($value, '%') !== FALSE) {
      $fake_item = array(
        'alter_text' => TRUE,
        'text' => $value,
      );

      // Row tokens might be empty, for example for node row style.
      $tokens = isset($this->row_tokens[$row_index]) ? $this->row_tokens[$row_index] : array();
      if (!empty($this->view->build_info['substitutions'])) {
        $tokens += $this->view->build_info['substitutions'];
      }

      if ($tokens) {
        $value = strtr($value, $tokens);
      }
    }

    return $value;
  }

which is where the error Deprecated function: strpos(): Passing null to parameter #1 ($string) of type string is deprecated in views_plugin_style->tokenize_value() (line 156 of /plugins/views_plugin_style.inc) might be coming from, unless $value is checked before calling the function?

I haven't dived in to see how many of these instances represent places where the first argument to strpos could be null at runtime, but there are a bunch. I excluded ones found in tests for now.
