commit 05bdcbbee3e8b10e4ae6a6086a863ecc4f2c17ba
Author: Pedro Santos <[email protected]>
AuthorDate: Sat Oct 3 12:59:24 2026 -0300

    Escape the starting text of the upload progress bar
    
    UploadProgressBar reads the text it shows while an upload starts from the
    application's resource bundles and writes it into a JavaScript string 
literal of
    its initialization script as it stands. A translation carrying an 
apostrophe did
    not hold as the literal it was pasted into, and the javadoc invites one by 
naming
    the resource key for customising that text. It now goes through
    JavaScriptUtils#escapeQuotes, as the delete label of MultiFileUploadField 
does.
    
    The ids the same script writes stay as they are: an id is restricted where 
it
    enters, and a text from a bundle is not.
