SCUMM: INDY4: Dialogue skip passes several lines at once

[JohnnyWalkerDesign]

ScummVM v2.2.0
Fate of Atlantis CD Talkie
macOS 10.14.6 (Catalina)

PLAYING WITH SUBTITLES ONLY

When playing Fate of Atlantis, pressing "." (skip dialogue) the game skips several lines at once. This means you miss important plot points.

As intended (and with all other Scumm based games), pressing "." skips the line visible on the screen. For some reason in FOA several lines are skipped at once.

For example, Heimdall in Iceland. If you ask him about the Atlanteans and press the . key, you will get Indy's reaction instead of just skipping the current line Heimdall is saying.

The can be seen again with Costa on the Azores. Ask him where Atlantis is and press . and you will get Indy's response without hearing him describe how the Azores is Atlantis.

As someone who has played through Scumm games for decades, I regularly use the . to skip dialogue I have read. I have never had this issue before. Thanks!

I tested the Azores scene with several versions (DOS, FM-Towns, Amiga). The dialogue when I click on "I hear you know something about Atlantis" is always like this:
Indy: "I hear you know something about Atlantis"
Costa: "Pah."
Costa: "Wouldn't tell you if I did."
Then I get three new dialogue options:

• "Come on. Be a chum."
• "Come on. I'm a fellow believer."
• "Then don't. Be jerk."

There is no difference whether I have speech or text enabled or both. Hitting '.' will work as intended.

I thought the bug desription wasn't quite right (you don't get to ask him where Atlantis is, he will ask you). So I tried this:

• click "I hear you know something about Plato's Lost Dialogue."

Costa: "Maybe so, maybe no."
Costa: "Who are you?"

• click "I'm a fellow believer."

Costa: "Is that right?"
Costa: "Do you know where Atlantis is?"

• click "Why yes, of course I do."

Costa: "Oh."
Costa: "Do tell."

• click "Somewhere under the ocean."

Costa: "No. No. No."
Costa: "Come closer, boy, and I'll tell you."
Costa: "You're STANDING on it!"

Still, I can hit '.' with speech or subtitles or both on any of Indy's or Costa's lines and it will only skip the current line. I am on Windows. Maybe it's something with the MacOS version. I'll see that I try Linux, later.

Here you go. I made a video demonstrating what I'm seeing. Look at what happens after I press "I'm a fellow believer." Costa's line appears ("Is that right?). I skip that and a bunch of dialogue is lost.

One thing I forgot to mention (really silly of me): I'm playing with Voices turned off. Only subtitles.
