Bug 179922 – Setting text with innerHTML on a node with fixed height does not clear out old text

• Status: RESOLVED
• Resolution: CONFIGURATION CHANGED
• Component: Text

If you use innerHTML = ... to replace the text in a DOM node, and

- the original text spans more than one line
- the DOM node has a fixed height
- the new text is shorter than the original text

the original text is not cleared out completely.
For example, if the original text is 4 lines and the new text is only 1 line,
3 lines of the original text remain.

Reproduced in Safari 11.

Apologies if this is a Safari issue - there's no way for me to test this.

(Make sure the text on init spans more than one line. Then click the button).

You're right - this is a WebKit (repaint) issue.

Hello, is there any updates on that bug? 
It seems to have high priority but is untouched since 6 months ago

I can't reproduce this issue with trunk. After clicking on the button, the old text is cleared properly. Do you mind checking with the latest build at https://webkit.org/build-archives/ to see if the repaint problem is still there?

I am unable to reproduce this bug in Safari 16.3 and it updates the text properly and don't have any lingering text issue.

Marking this as "RESOLVED CONFIGURATION CHANGED".
