Taking a look 👀

[neil-marcellini]

Nothing really jumps out to me from the list of PRs in this release, but maybe the theme switching has to do with it. I'll do a little investigation locally now.

[neil-marcellini]

Shoot, I'm really not sure what's going on here. The view is rendered by react-plaid-link in an iframe. I was able to pause and inspect the page by setting a debugger below this line, but I haven't figure out the root cause. My guess is that we somehow broke this when changing some of the root styles of the app. I'll ask for help in the Slack open source channel.

This issue isn't really a big deal so it shouldn't block the deploy

[grgia]

We cannot use root styling anymore, so we will need to handle this another way

Proposal

Please re-state the problem that we are trying to solve in this issue.

When Plaid modal is rendering, the background is transparent instead of white., which now looks like having two spinners on the same page.

What is the root cause of that problem?

We don't have color-scheme: dark !important; on :root any more so this happens.

What changes do you think we should make in order to solve the problem?

Add color-scheme: dark !important; in CSS to target the iframe of Plaid. We've done similar things with Onfido as well.

What alternative solutions did you explore? (Optional)

We can make the color scheme dynamic based on theme.colorScheme as well, but still targeting the iframe of Plaid.

[grgia]

@tienifr we cannot add that line back because we are adding a light theme to App

[tienifr]

@grgia we add it back but only targeting the Plaid iframe, it won't affect other components, or do you mean there'll be light theme for the Plaid background as well?

[grgia]

I more mean I think we should avoid any hardcoded colors via CSS and use a ColorSchemeWrapper instead. But you're correct that that would work for this specific case if we only target the iframe

[tienifr]

@grgia yeah but Plaid is 3rd party code so it won't work with our custom components, unless we ask the library authors to add a prop like colorScheme to their exposed hook, which I'm not sure they'll agree to.

I think it's better we treat it as 3rd party code and have a CSS file like we did for Onfido here, and make sure it doesn't impact other components, which will of course follow our color scheme pattern.
