Created attachment 410580 [details] Min repro for the bug The input element receives focus but does not scroll into view if you call focus() and a selection API on an input element with the step attribute (except when the exact text selection was already set). Repro: 1. input type=text with the step attribute set. Note: Any value for step seems to work. I use the empty string. 2. Scroll input off-screen 3. Send focus and set selection at the same time. - Note: Setting the selection via any of the selection APIs hits the bug: .select(), .selectionStart and .selectionEnd together, or .setSelectionRange(). - Note: The selection being set must be different than the current selection to hit the bug. - Note: If you click one of the select buttons on the left twice in a row, the input will scroll into view because text selection was unchanged. Version: Tested in Safari 14.0 (15610.1.28.1.9, 15610) and Safari Technology Preview (Release 113, Safari 14.0.1, Webkit 15610.2.3.1). I expect it also happens in Safari 13 based on the bug report I was investigating when I reduced to this min-repro. Tested on Mac desktop only. Test file attached with min repro.

FYI, originally discovered on Salesforce.com but there is no public URL for that repro. No repro in Chrome 85.

This actually doesn't require the step attribute.

Created attachment 410698 [details] Repro without step attribute A simpler repro that doesn't include the step="" attribute on the input.
