JavaScript exceptions when using the PDFViewer with the latest PDF.js version

[IvanDanchev]

Bug report

Using the PDFViewer with the latest version of PDF.js (3.9.179) throws js exceptions. Version 3.4.120 is the last one, with which no js exception is thrown.

Reproduction of the problem

Dojo example: https://dojo.telerik.com/IHedIhur/3

1. Open the devtools console and run the example.

Current behavior

The file is loaded, however, js exceptions are thrown:

The --scale-factor CSS-variable must be set, to the same value as viewport.scale, either on the container-element itself or higher up in the DOM. text_layer.js:480:14

Expected/desired behavior

No js exceptions when using PDF.js versions newer than v3.4.120.

Environment

• Kendo UI version: 2023.2.718
• jQuery version: x.y
• Browser: [all]

Hello, before in my code I had

<div class="min-h-[400px] w-full">
	{#if browser}
		<Document
			loadOptions={{
				url: '...'
			}}
		>
			<div>
				<Page/>
			</div>
		</Document>
	{/if}
</div>

Now I have

<div class="min-h-[400px] w-full" style="--scale-factor: 1;">
	{#if browser}
		<Document
			loadOptions={{
				url: '...'
			}}
		>
			<div>
				<Page/>
			</div>
		</Document>
	{/if}
</div>

You can try adding style="--scale-factor: 1;" to the container of your pdf

I am closing this issue because it is no longer reproducible using jszip 3.10.1 and Kendo UI 2023.3.1114. I am linking a working Dojo example - https://dojo.telerik.com/@sspasova/UqIlAtuz

Reopening, since the issue is still reproducible with PDF js versions newer than 3.4.120.

The issue is not reproducible all the time. On my side I reproduce it with https://dojo.telerik.com/@sspasova/UqIlAtuz on Chrome 122 when running the Dojo. But the issue is not reproducible on my side in Firefox or if I open the Fullscreen version of the same Dojo in Chrome https://runner.telerik.io/fullscreen/@sspasova/UqIlAtuz
