After some time debugging it and a lot of JS performance improvements it might actually be some rendering issue in IE, and not something related to the two-way data binding. The "UI Responsiveness" debugger in IE shows that it spends most of its time when it blocks in "Style calculation".
It might be some issue with flexbox (which is somewhat strange in IE anyway) because of which it spends most of its time rendering. I'm still investigating, there are a lot of bug reports for these kinds of issues, but I didn't see a current one so far.
IE has problems rending even 50 watchlist events at once, while Chrome does ~1000 easily.
