Steps to reproduce the issue

Hi
I have plugins for my extensions, which display map in lightbox, and it works correctly in joomla 4.x, for example, I tested it on 4.4.6
And the same version of my plugin (the same code) doesn't correctly work in 5.1.2

I get my code and rewrite it to use com_content (article) to display

Here my PHP code to produce link to popup and modal

$popupCall = Route::_('index.php?option=com_content&id=2&tmpl=component&view=Article'
				, false);

$replacementsLght = '<a class="zhgm-modal-button" title="test" href="'.$popupCall.'" rel="noopener noreferrer" data-bs-toggle="modal" data-bs-target="#linkModal">do test</a>';

$replacementsLght .= HTMLHelper::_(
			'bootstrap.renderModal',
			'linkModal',
			array(
				'url'    => $popupCall,
				'title'  => $popupTitle,
				'height' => $popupHeight,
				'width'  => $popupWidth)
		);     

after that I do echo where I need to have this code.

Expected result

Link with text and when press link - get lightbox with article with id=2

Actual result

You have link, and when press you'll get popup with title but without article

There is no any code in div section with class="modal-body"

System information (as much as possible)

Joomla 5.1.2

Additional comments

When I write example I noticed, that Route::_ is case sensitive for view name (I mean that if i wrote view=article, Route return incorrect value at all). It is as for 4 as for 5 version
