multiple calls to the update function

[peterprvy]

Sorry, my english is bad (I use a translator)

When the text in the textarea is changed, the update function is called in oninput

in it, setting the value causes an update again (in the attributeChangedCallback function)

        /* Syntax-highlighting functions */
        update(text) {
            if(this.value != text) this.value = text; // Change value attribute if necessary.
            if(this.querySelector("textarea").value != text) this.querySelector("textarea").value = text; 

assignment this.value = text; generate attributeChangedCallback

        attributeChangedCallback(name, oldValue, newValue) {
            if(this.isConnected) {
                // This will sometimes be called before the element has been created, so trying to update an attribute causes an error.
                // Thanks to Kevin Loughead for pointing this out.
                
                this.plugin_evt("attributeChanged", [name, oldValue, newValue]); // Plugin event
                switch (name) {
    
                    case "value":
    
                        // Update code
                        this.update(newValue);

My solution:

        /* Syntax-highlighting functions */
        update(text) {
            if(this.value != text) {
                this._inUpdateNewText = text;
                this.value = text; // Change value attribute if necessary.
                this._inUpdateNewText = undefined;
            }
            if(this.querySelector("textarea").value != text) this.querySelector("textarea").value = text; 

        
        attributeChangedCallback(name, oldValue, newValue) {
            if(this.isConnected) {
                // This will sometimes be called before the element has been created, so trying to update an attribute causes an error.
                // Thanks to Kevin Loughead for pointing this out.
                
                this.plugin_evt("attributeChanged", [name, oldValue, newValue]); // Plugin event
                switch (name) {
    
                    case "value":
    
                        // Update code
                        if(this._inUpdateNewText === undefined || newValue !== this._inUpdateNewText) {
                            this.update(newValue); 
                        }
        
                        break;

Thank you for this. I will add your solution to the code as soon as possible.
