snapshots are not consistent on firefox

[maximegheraille]

Hi,

I created this issue in the tool we use to take snapshots but it seems the issue is related the how jest takes snapshots simonsmith/cypress-image-snapshot#63

we currently have components where we have assets some text. All snapshots are taken on firefox, chrome and edge with https://github.com/simonsmith/cypress-image-snapshot

Both edge and chrome are always fine, but firefox keeps randomly failing them because the image seems different (which is not case).

my setting are as follows

const options: CypressImageSnapshotOptions = {
			failureThreshold: 0.01,
			allowSizeMismatch: true,
			failureThresholdType: 'percent',
			capture: 'viewport',
			comparisonMethod: 'ssim',
			customSnapshotsDir: `./cypress/reports/mochareports/snapshots/${Cypress.spec.fileName}`,
			e2eSpecDir: Cypress.spec.relative,
			snapFilenameExtension: '.snap',
};
