Scrolling Select2 inside of Table2 causes Table2 to also scroll

[easternmotors]

Environment

• Package version(s):

@blueprintjs/select: 4.5.1
@blueprintjs/table": 4.4.1

• Operating System: Windows 10 Pro Version 21H2
• Browser name and version: Brave Version 1.41.100 -- Chromium 103.0.5060.134 (Official Build) (64-Bit)

Code Sandbox

Minimal repro: https://codesandbox.io/s/blueprint-sandbox-forked-tbjtm1?file=/src/Table2Example.tsx

Steps to reproduce

1. Click on one of the dropdowns
2. Attempt to scroll down

Actual behavior

The Table scrolls and the Menu scrolls.

Expected behavior

The Table does not scroll and the Menu scrolls.

Possible solution

Not sure. I've tried a bunch of things but nothing seems to work. Settings boundary on Table's popoverProps is what I expected to initially work but it didn't. It is also weird that even if the Menu is outside of the Table bounds and you scroll, the Table still scrolls.

One note: If you change the height and width in app.css to both 100%, the Table does not scroll as expected.

I made a small fix to your sandbox by adding in blueprint-popover2.css but this looks like a tricky issue... I think we may need to provide an option to stop propagating scroll events from inside QueryList (Select2, Suggest2, MultiSelect2) popovers... otherwise the scroll events will bubble up to the Table like they do in your example.

If you add the following to the Select/Popover component, it can prevent the popover content scrolling event propagating into Table element.

// for Select2
popoverContentProps={{
    onWheelCapture: (event) => event.stopPropagation()
}}

// for Popover2
backdropProps={{
    onWheelCapture: (event) => event.stopPropagation()
}}
// or
content={
    <div onWheelCapture: (event) => event.stopPropagation() />
}

In your given example, add the following:

<FilmSelect
    ...
    popoverContentProps={{
        onWheelCapture: (event) => event.stopPropagation()
    }}
/>

For table quadrant scrolling event propagating into body element, I used the following CSS to handle it:

.bp3-table-quadrant-scroll-container {
    overscroll-behavior: contain;
}
