Component#replaceText not replacing content as expected

[emilyy-dev]

Description

Component#replaceText does not seem to behave as one would expect, it appears it is appending the resulting replaced component to the original component, but this does not seem to happen on nested hover event TextComponents, I wouldn't know about other components (translatable, NBT, selectors, etc) or any other specifics about this issue (mainly because I want to waste as little time as possible, but I'll gladly try out other possibilities if needed!!).

This is what it looks like for playerprofiles load <profile> as only element in replacements (in the case of the hovered event).
I would expect to see /playerprofiles load <profile> like in the hover message, not /{0}/playerprofiles load <profile>.

Sample Code

public enum Message {
  USAGE_COMMAND(text().append(text("/{0}", RED))
                      .hoverEvent(text().append(text("Click to run"))
                                        .append(space())
                                        .append(text("/{0}", GRAY))
                                        .build().asHoverEvent()));

  private static final Pattern INDEX_PATTERN = Pattern.compile("\\{(\\d+)}");

  private final Component component;

  Message(final ComponentLike fromBuilder) {
    this.component = fromBuilder.asComponent();
  }

  public void send(final Audience audience, final Identity identity, final String... replacements) {
    final Component replaced = component.replaceText(INDEX_PATTERN, builder -> {
      final Matcher matcher = INDEX_PATTERN.matcher(builder.content());
      matcher.find();
      final int index = Integer.parseInt(matcher.group(1));
      return text(replacements[index]);
    });

    audience.sendMessage(identity, replaced);
  }
}
