Conditions (IFs) does not get updated inside transition blocks.

To Reproduce
https://svelte.dev/repl/60298ac9b7854a6a99b814fb17e54353?version=3.23.0

Repl Description
In this repl there are three buttons. First one toggles a transition and display a hidden block. Inside this block there are two more buttons which change value b that has conditions on it and after changing a value the block gets hidden.

The problem is variable b inside template is not getting updated nor before nor after the out transition. It is only updated when first button is clicked once again, to reveal hidden element.

Same happens if I use stores instead of reactive variable b. Which is how I've discovered this problem in my project.

Expected behavior
Variable b is updated before transition is run.

Use tick before toggleA() and it seems to work fine :)

Thanks, this works.
Still I'm not really sure that current behavior is intentional.

UPD: now I think I better understand how it works and why it works like that, thanks.
