Conversation
layoutShift tracking can loop until the browser throws RangeError: Maximum call stack size exceeded. Passing { layoutShift: false } through autoUpdateOptions stops that, and the option is left off steps that never set it.

Preserve tour defaults when step options change.
mergeTooltipConfig() runs in _setOptions(), but updateStepOptions() uses Object.assign() and does not recompute the merged configuration. For a mounted step, the update rebuilds the elements and calls setupTooltip() immediately. A later setup can therefore pass { elementResize: true } to autoUpdate() without the tour’s layoutShift: false.
Merge autoUpdateOptions before applying the update:
Suggested fix
updateStepOptions(options: StepOptions) {
- Object.assign(this.options, options);
+ const updatedOptions = options.autoUpdateOptions
+ ? {
+ ...options,
+ autoUpdateOptions: mergeTooltipConfig(this.options, options)
+ .autoUpdateOptions
+ }
+ : options;
+
+ Object.assign(this.options, updatedOptions);🤖 Prompt for AI Agents
