Case1. [ Ctrl+A ]

1. Open the attached HTML file(tableSample.html) in the Chrome browser.
2. Press Ctrl+A (or Cmd+A) to select all.
3. Typing Korean characters with a keyboard.
4. The table collapses into a single row (table structure is disrupted), and the input text appears in the second cell of the table.
5. Press Ctrl+Z, then press Ctrl+A.
6. Typing non-Korean characters such as English letters, numbers, or symbols using a keyboard.
7. The table disappears, and the text is entered directly below the contenteditable area.

• Actual result: Step 4 and step 7 are different.
• Expected result: Step 4 and step 7 are the same.

Case2. [ drag select or shift + click select ]

1. Open the attached HTML file(tableSample.html) in the Chrome browser.
2. Select the entire table by dragging across all cells.

or

Click on the cell in the first row, first column to position the cursor, then hold down shift and click on the cell in the second row, second column to select all cells in the table, and then release shift. 3. Input any character via the keyboard, whether it's Korean, English, or any other.

• Actual result: The table collapses into a single row (table structure is disrupted), and the input text appears in the second cell of the table.

Problem Description

When selecting a table and typing characters, the Table structure is disrupted (its form changes).

Could you please check if this is a bug?

The issue of the table structure changing and text being entered within it when typing after a full selection, as in Case 1, only occurs when typing Korean characters.

For Case 2, as the issue occurs regardless of whether Korean or any other characters are entered, I would appreciate it if you could inform me whether this is considered normal behavior.

If both Case 1 and Case 2 issues are bugs, I would appreciate it if you could confirm and fix them to ensure consistency.

Thank you for checking.
