> Both seem to blink off and not come back now. Not sure when that second text animation regressed.

Behavior has changed several times here, actually.

* Nightly 2009-12-31: first line blinks away & stays missing, second line blinks. (as described in comment 1)
* Nightly 2010-12-31: first line is visible (not blinking), second line is missing entirely.
* Nightly 2011-12-31: first line is visible (not blinking), second line blinks.
* Nightly 2017-12-31: (same as above)
* Nightly 2018-12-31: first line blinks away & stays missing, second line blinks away & stays missing.
* Nightly 2024-10-17: (same as above)

So I think our behavior was unchanged from the end of 2011 through the end of 2017, and then there was a change at some point in 2018, and our behavior's been unchanged since then.

I'll try to get a regression-range for that 2018 regression.

So I think our behavior was unchanged from the end of 2011 through the end of 2017, and then there were two regressions in 2018, and our behavior's been unchanged since then.

I'll try to get a regression-range for the 2018 behavior-changes.
