Product:Safari Product Version:11.0 (13604.1.25.3.3)
Classification:UI/Usability Reproducible:Always
 
Summary:
When a webpage updates its title dynamically, this is not reflected on its Safari tab.

Steps to Reproduce:
1. Create a web page that has no <title> tag and updates its title dynamically using <script>document.title = "Test";</script> or with a dynamic counter, and have the page refresh itself using setTimeout(location.reload, 10000) or so.
2. Save a bookmark to this page and call it "Demo".
3. Open a new tab with this bookmark.

Expected Results:
The tab label should read "Test".

Observed Results:
The tab label reads "Demo".

Version:
Safari Version 11.0 (13604.1.25.3.3)
macOS High Sierra Developer Beta 2 Update 1 (17A291m)

Notes:
Please take a look at the attachment where the number of items in the list was 7 when the page loaded and is now 4 only. The tab title still says "7 in work" though.

July 10 2017, 11:03 PM Please find attached a sysdiagnose generated for Safari (uploading soon). The second attachment shows you the source code for a tab that has the title "XX", was called from a bookmark labelled "XX", but the source code JavaScript should cause the document title to change to "0 new, 7 in work - XX", which it did not. This used to work in previous versions of Safari (Sierra).
