Filter is not working if ximgdiff is disabled

[stevschmid]

Describe the bug

If ximgdiff is disabled in regconfig.json, filtering in the generated HTML report is not working.

Reproduced step

Check out reg-cli-report-ui, disable ximgdiffConfig in develop/index.html

ximgdiffConfig: { enabled: false, workerUrl: './worker.js' },

Start the dev env via yarn start. Filtering is not working.

Cause

reg-cli-report-ui/src/worker-client.ts

Lines 44 to 46 in 73849df

	if (!enabled || !workerUrl) {
	return;
	}

this._worker is only created if ximg diff is enabled. Since this._worker is used to relay the filtering messages, the filtering is not working if XIMGDiffConfig.enabled = false

Expected behavior

Filtering is working even with ximgdiff disabled.

Actual behavior

Filtering is not working with ximgdiff disabled.

I'm using Loki for visual regression testing, but I'm using reg-cli for reporting, as some other Loki users are doing (found about reg-cli in this issue oblador/loki#76).

I'm experiencing the same issue with filtering, it would be helpful to have it working or at least have a workaround. Could someone please check on this?
