Configuration:

• Web browser and its version: IE11
• Operating system and its version: Windows 7
• PDF.js version: 1.5.214
• Is an extension: No

Steps to reproduce the problem:

1. Search for 'the' in the link provided above.
2. Do next repeatedly and you should see the page jumping up before it shows the highligted result

What is the expected behavior? (add screenshot)
It should not jump like other browsers (Chrome, Firefox and Safari)

What went wrong? (add screenshot)
Page jumps when you scroll

This effect is actually, technically, present in all browsers, it's just that with the usual exception of IE 11 every other browser is fast enough that it's completely imperceivable. The explanation is that the current page is always being re-scrolled into view, when a match has been found, regardless if it's necessary or not; see

pdf.js/web/pdf_find_controller.js

Lines 473 to 478 in 81f5835

	if (this._scrollMatches && this._selected.pageIdx === index) {
	// If the page is selected, scroll the page into view, which triggers
	// rendering the page, which adds the text layer. Once the text layer
	// is built, it will attempt to scroll the selected match into view.
	this._linkService.page = index + 1;
	}

Most likely this issue could be somewhat easily fixed, perhaps along these lines, but I'm just not sure if you want to bother with it!?

I would say we close this as won't-fix since it's not really a problem in modern browsers.
