ThemeRoller seems to have issues with multiple open tabs

[GSPP]

(Migrating issue https://bugs.jqueryui.com/ticket/15174 since I posted to the wrong bugtracker.)

ThemeRoller behaves really weirdly in the presence of multiple open tabs.

1. Open a tab, make a customization (border radius = 0).
2. Ctrl-F5 to confirm the change was remembered (it was).
3. Copy the URL to a new tab. Observe that the corner radius text box was reset to some other value (3px). But the page still looks like 0px.

Very hard and inconsistent to repro. I hope I got the steps right.

Related bug:

1. Perform steps 1 and 2.
2. Click download. On the download page click "design a custom theme". To go back. Observe, that the corner radius has been reset to 3px. Font family was reset for me as well (I had cleared it). Weight and size were remembered correctly.

Also, sometimes values that are not touched at all reset to base values. I just changed the corner radius back to 0px without clicking any button or link and without reloading. Then, all the colors changed to the base theme.

Hi,
while researching regarding my issue here https://forum.jquery.com/topic/saved-themeroller-theme-shows-wrong-values#14737000007330003 I came across your issue:

You wrote

as if it would be a well known workaround for my issue (it fixes my issue).

I'm still unsure if my issue is a bug or a well known behavour.
