Uncaught rejected promise when attempting to fetch flags while offline

[frankieyan]

Hi there 👋 I'm seeing an uncaught rejection when calling Flagsmith.init while offline.

It seems to be coming from this call:

flagsmith-js-client/flagsmith-core.ts

Lines 447 to 449 in f2c2964

	if (shouldFetchFlags) {
	// We want to resolve init since we have cached flags
	this.getFlags();

It doesn't cause any real issues as flags are still resolved correctly from local storage, and since the user is likely offline when this happens, it may not affect our telemetry. However, since it's not an error that can be caught in user land, perhaps it'd make more sense to handle the rejection and only reject from init() if the cache fails.

Please let me know if you need more details, thank you!

Hi @frankieyan, thanks for raising this. I think your suggestion here makes sense

handle the rejection and only reject from init() if the cache fails

Would you be willing to submit a PR for this?
