The maxlength attribute of a text input field is not being respected

[AmarBouchibane]

Hi, I'm using pdf.js 5.7.284 in an iFrame and have a PDF that allows an input field with a maximum of 5 characters. However, pdf.js allows more than 5 characters to be entered. Here's what the HTML for the input element looks like:

<input type="text" value="" data-element-id="230R" name="Postleitzahl" tabindex="0" required="true" aria-required="true" maxlength="5" id="pdfjs_internal_id_230R" style="overflow-x: hidden; font-size: calc(8.4px * var(--total-scale-factor)); color: rgb(0, 0, 0); background-color: transparent;">

Best regards,
Amar
