PDFJS rendering pdf with different pages orientations (text layer) - pdf.js

Question

I use PDF.JS to annotate PDFs on my website.
It works fine, but I have a problem with the "Text Layer" when the PDF contains pages in different orientations (portrait and landscape).
Here is a screenshot that shows the situation:

Here is my code:
function renderPage(pageNumber, canvas, annotationLayer, textLayer) {
__PDF.getPage(pageNumber).then(function(page) {
viewport = page.getViewport({
scale: __SCALE
});
canvas.height = viewport.height;
canvas.width = viewport.width;
var renderContext = {
canvasContext: canvas.getContext('2d'),
viewport: viewport
};
// Render the page contents in the canvas
page.render(renderContext).promise.then(function() {
return page.getTextContent();
}).then(function(textContent) {
console.log(pageNumber, textContent);
var textLayer = new pdfjsLib.renderTextLayer({
container: $('.page-container-' + pageNumber + ' .text-layer').get(0),
pageIndex: page.pageIndex,
viewport: viewport,
textContent: textContent,
enhanceTextSelection: true,
});
// Clear HTML for text layer and show
$('.page-container-' + pageNumber + ' .text-layer').html('').show();
// Assign the CSS created to the text-layer element
$('.page-container-' + pageNumber + ' .text-layer').css({
height: canvas.height + 'px',
width: canvas.width + 'px'
});
})
});
}
PDF with only landscape or only portrait pages work fine...
Thanks for your help!
