1860309 - Almost continuous bailouts and Invalidations on https://bundlejs.com in part of the js-heavy profile

Status: NEW

(Core :: JavaScript Engine, task, P3)

Description

[Mayank Bansal]

First the profile : https://share.firefox.dev/3tHInNb (focus on the Dom Worker thread17592)
Tons of Bailouts and invalidations wherever you see JS in that thread. You can look at the ~2.2 second chunk right at the beginning. For this chunk of time, the profiler also suggests that 30% (40% of 70%) time is spent in Baseline.

STR: Go to https://bundlejs.com
Put this in the input box :
// Click Build for the Bundled, Minified & Compressed package size
export * from "d3@7.8.5";
export * from "d3-milestones@1.4.7";
export * from "@cbinsights/react-d3-graph@1.3.0";
export * from "d3-org-chart@3.1.1";
export * from "d3-org-chart-jc@2.6.16";

Click on Build button.
Wait and wait. The js-heavy bit comes only at the end

I guess this is how "real-world" js code behaves, so feel free to resolve as invalid.
