[Bug] Timer doesn't align the real time after pausing

[yozyyyqls]

Description

When pausing the timer before it finishes, although the UI of the countdown seems right, the wave animation becomes slower than before. For example, you set up a 1 min timer. You pause the timer at 30s. Then you resume it. The duration of wave animation should be 30 seconds instead of 1 minute.

What happened?

How to reproduce the bug:

1. Start a timer of any duration.
2. Pause the timer before it finishes.
3. Resume the timer.
